Take it with a grain of salt because my experience is all of one time -- but I was able to get on one of those trampolines and thought it really stunk -- as in no fun. I envisioned being able to get a good bounce and then get some big cannonballs off the tram into the lake. No dice -- I think with it floating it is just not enough of a solid platform to really function like the tramp should. Either that or maybe the one I was one was just underinflated. For kids, maybe not an issue.
