Our hot tub arrived last Sunday (Mother's Day) -- been in it nearly every night since! Now I can relate to all the hype. I feel great.
I think I've discovered another cause of the "floating" syndrome. Aside from needing sculpted seats, you need to "relax" (like only an experienced hot-tubber can do) The first 2 times in our hot tub, I was disappointed to find I was floating a bit (didn't so much when I wet-tested?). But on the 3rd time in, and every time since -- no floating! So I think I was wound up in a tense ball, and was be pushed around by the jets -- but once I trusted the water depth and laid back and relaxed, no more floating!
So far, we love our tub.
