I agree with what everyone has said here.
However, if your kids enjoy the clubs/labs, you will be able to enjoy the adult beach and pool while they are in the kid's programs. What you can't do (not sure if you meant to do this, or people just assumed you did) is leave your kids unattended at the pools. I will say that there were kids in the lab with my kids who went by themselves to the goofy pool. We saw one pair of brothers (9 and 11 or so) everytime we took the kids to the goofy pool, and their parents were nowhere around (They were near our dinner table, so I knew what their parents looked like). These boys were constantly roughhousing in the pool, and whenever it got bad, we just left. I did think about saying something to their parents at dinner, but decided against it.
