My sister surprised us for my birthday with one of those over the water cabanas. I would never have wasted the money. I was bored within a half hour. The "sandy bottom" is slimy and full of small barnacles around the one we had. The food was good, but too much of it, and very slow (we got ours an hour later than promised).
The worst thing...as I posted...is what the heck with the distance to the bath rooms??!! And when you get there...they are small with a long line. Yikes. OK..so pee in the ocean (which does not help with keeping it clean and clear in that area IMHO)......but what if you have to do something else?
