My initial post on "Trouble in Hawaiian Paradise" might have painted an unrealistic picture of my island home. I think it's worth clarifying the real picture versus what my idealistic traveler self sees in Hawaii. So, being "real" for a moment, I must admit that Hawaii, just like other expensive and desirable travel destinations on the globe, certainly feels the effects of a decline in tourism. One particular Gadling reader brought specific issues to my attention that I'd like to discuss in greater detail in order to illustrate Hawaii's predicament more accurately and clearly.

Newer, more exotic, less expensive destinations are changing the landscape of options for travelers. These new destinations (like Laos, Slovenia, and Mongolia) have changed people's approach to travel. In most cases, it is not only more cost effective but also better to go elsewhere. Hawaii has always been expensive. That has not changed. What has is that tourists who don't necessarily want or have to come to Hawaii choose other destinations with similar climate, like Mexico and Costa Rica. These places are certainly more affordable, but the cultural experience is quite different. Many travelers will still pay the extra cost so they can experience "Hawaii." Others will not.

Russian architect Alexander Asadov is fighting global warming with innovative building designs. His latest concept is a floating Aerohotel, pictured above. This floating island features a 200-meter hub containing hotel rooms or residences, cafes, winter gardens, and restaurants.

The Aerohotel is held aloft by a system of supports and three main legs anchored to the bottom of the site, and unlike man-made islands with tons of gravel fill, this design preserves the aquatic ecosystem below. Asadov's studio states that the construction costs and environmental impact of his design are significantly lower than gravel works projects.

This design can be installed in any body of water, and the plan includes docks for boats and a landing strip for zeppelins. Because if you're cool enough to live in a floating island, you're cool enough to travel by zeppelin.

The design is certainly interesting and futuristic, but is it aesthetically pleasing, or is it an eyesore? The idea is very appealing, but I'm not yet sold on the look. What do you think?

This Sunday's Columbus Dispatch travel section is devoted to Caribbean travel. With this morning's post on Caribbean vacations, written before the Sunday paper arrived on my front porch, I'm wondering if I'm getting a message.

One article, "Caribbean offers comfort for less cash" by David Swanson points out an option not mentioned in today's earlier post--Tobago. After reading about all of Tobago's high points, I'm hesitant to let the word out because, frankly, I want the bargains to be there when I show up.

Here's why Tobago sounds fantastic:

I don't know about you, but this time of year when the sky is slate gray more often then it's sunny, and the leaves have dropped from the trees like rain, I start thinking about warmer pastures. "Let's get out of Dodge," I say. Not really, but that's what I fantasize.

The Caribbean has been an appealing option since a couple of years ago a friend asked me if I wanted to go to Costa Rica. Although, Costa Rica isn't part of the Caribbean scene exactly, it got me thinking about that part of the world. Our trip didn't work out and remains unfinished business. This article in The New York Times offers oodles of option ideas for a Caribbean vacation from the pricey to the not so bad. Now, I'm thinking again.

One of the reasons for the Caribbean travel deals is the beating that the weather gave to the area this year. The financial meltdown is another. Just like Las Vegas has become cheaper in order to draw tourists, so has the Caribbean.

The article touts Anguilla, Bahamas, Barbados, Curaçao, Dominica, Dominican Republic, Grand Cayman Island, Grenada, Martinique, Jamaica, Puerto Rico, St. Marten, St. Kitts, St. John, St. Lucia, Turks and Caicos and Tobago.

Each destination has a different appeal depending on what you're after.

Mayor Bloomberg's office has urged, urged, urged people in New York City to use cloth grocery bags for a long time now. They've cajoled. They've pleaded. His office has set up plastic bag recycling receptacles at various supermarkets around the city in an effort to make the city folk more environmentally conscience.

But people just love, love, love those plastic bags. They just can't stop using them. Now, there's another plan in the pipeline. You can use those handy sacks of thin plastic, but it might cost you. If the plan goes in the direction Bloomberg would like, people who want their groceries sacked in plastic will pay 6-cents per bag at check-out.

This very European move-- the New York Times article cites many European countries as having similar measures, would generate income for the city. The $16 million would come in handy each year when it comes to doling out the budget.

Some say that 6-cents won't make much difference in people's sack habits and the fee should be much higher. How much higher? When people in Ireland had to fork over 33-cents for a plastic bag starting in 2003, plastic sack use dropped by 94-percent.

Bloomberg thinks 6-cents is a good place to start. Seattle is considering similar measures and Los Angeles and Dallas have also studied ways to get people to stop using plastic like there's no tomorrow.

Perhaps if eco-friendly shopping bags became more of a status symbol, and using plastic became so low brow that people who used them would be so embarrassed they'd feel compelled to duck their heads as to not be noticed, people's habits would change.

At any rate, if you're visiting New York City and duck into a deli for a snack, consider forgoing the bag. Bloomberg will thank you.

Here in the US, we recycle but we don't always see what our waste goes to. Not so in Thailand where recycling takes on new meaning at the Buddhist temple Wat Pa Maha Chedi Kaew, 370 miles northeast of Bangkok in the Si Saket province. Also known as Wat Lan Kuad, or "Temple of Million Bottles," the temple uses discarded bottles to construct everything on the temple site from the crematorium to toilets.

All in all there are about 1.5 million recycled bottles in the temple, and those at the temple are committed to recycling even more. "The more bottles we get, the more buildings we make," Abbot San Kataboonyo told Reuters.

Recycling doesn't stop at bottles; mosaics around the temple, mostly of Buddha, are made out of bottle caps. Besides being green, the recycled bottles don't fade, provide great light and are easy to maintain. Sounds like a pretty cool green location to put on your next eco-tour of Southeast Asia.

With fall foliage reaching its peak, I was reminded of a zipline tour canopy tour I took through the trees in Ohio this past June.

There are several zipline tour options. Pennsylvania, West Virginia, North Carolina and South Carolina also have zipline adventure offerings, although not all are canopy tours.

In an Escapes article in the New York Times, Roger Mummert gives a humorous account of his own experience at Ski Mountain Ski Area in Pennsylvania where he went with his teenage daughter for a bonding outing.

At the end of the article, he summarizes the highlights of each of the following places:

• Spring Mountain Ski Area, Spring Mount, Pa.
• Snö Mountain Ski Resort, Scranton, Pa.
• Nemacolin Woodlands Resort, Farmington, Pa.
• Hocking Hills Canopy Tours, Rockbridge, Oh.
• Ace Adventure Resort, Oak Hill, W.Va.
• Passages to Adventure, Fayetteville, W.Va.
• Organ Cave, Ronceverte, W.Va.
• Scream Time Zip Line, Boone, N.C.
• Carolina Adventure World, Winnsboro, S.C.

After visiting each Web site, I noticed that several have Halloween activities. Remember, zipline tours are truly for a multiage crowd. I was happy to see that the Hocking Hills Canopy Tours made it to Mummert's list. I had can still recall the whirring sound the cable made each time I zipped across.

The Penjari Biosphere is a wildlife preserve in a remote corner of the West African nation of Benin. Like many such wildlife areas, it struggles with poachers and environmental problems, but tourism, in the form of photo safaris like the one in the video, is an important source of income for the area.

Even the most jaded tourist, wary of tourist traps and non-authentic experiences, would find a safari like the one in the video exciting. The fact that getting up-close and personal with wild animals is an attractive proposition is nothing new to the African tourism industry, but fully capitalizing on the tourist potential while protecting the wildlife for future tourism is the challenge. But, there are now economic reasons for creating a sustainable tourist model. The more interest in wildlife tourism grows, the more demand there will be for sustainability.

This video was taken in early morning, when the Penjari's animals all head for the nearest watering hole. Check out the menacing elephant about a minute-and-a-half in.

Back in June, when I zipped from sycamore to oak trees along the highwire cable lines of the Hocking Hills Canopy Tours in the Hocking Hills region of Ohio, I thought, I bet this is gorgeous in the fall.

Now that yellows and reds are just beginning to show their colors, I'd say trees will be in their autumn glory in a week or two. Cold has arrived at night to hasten the palate switch. Meg's posts about fall foliage tour options, reminded me of this one.

I blogged about this tour before I took it, and am not surprised that it has remained so popular that the season has been extended through November--although the hours will change.

As a person with first-hand experience, I can vouch for the thrill of heading off on a wire from one tree to another. My favorite parts were the sections where I was zipping through the air, far from the platform I had left, high above the ground, and the platform where I was heading had yet to come into view. There is a moment where you can't see where you are exactly because of the leaves. Then, the next platform comes into view like a surprise of "oh, there you are."

If you kept up with Gadling this week, you've probably gathered some tips to help you plan your next trip whether you're looking for the practical or the extravagant. For example,

1. Aaron says that almonds make perfect travel snacks, something he knew about even before he read about it at the Happiness Project website that recently offered up vacation tips.
2. Jerry found out from Mark Jolly, editor of globorati, that train travel is one way to go to travel green, and that train travel is having a comeback. There are other travel tidbits besides. If you missed this post, check it out.
3. Scott pointed us towards a High Sierra luggage deal at Amazon.com
4. Meg told us how to have the ultimate diamond and jewelry shopping experience in Manhattan
5. And Anna pointed us towards environmentally friendly cities for a vacation. It may surprise you that Bangkok is on the list. It has a well-deserved spot.

Have a great weekend and enjoy watching the rest of the Olympics. I'm loving learning more about China from all of the side stories.
