Wow, no. I wouldn't want to demonstrate what happens when you land on a stingray! Cool looking, though!
The huts seen pricy. I bet it's a unique experience, though. It might be more economical to buy or build a house boat, especially now that scientists have proven that rocking helps you sleep.
I love how naturally angry the stingrays look, but I didn't get a good photo of that...next time :)
Very pricy huts, and yes, some of them are fantastic, but I think you have a great idea...heck, even a tarp over dingy too :)
