Tent Camping on the Water

What could be weirder... or maybe I misspoke, COOLER than this???  I've never been a huge fan of camping in a tent.  Mostly because of the uncomfortable factor.  But maybe this would feel more like a water bed???

Although- what happens when you need to get up?  You know, bathroom breaks and such?  Or... worse, what happens if some water critter decides to visit you?

Could be a bit scary.
