Well this slightly older 10 yo (ok by a decade or two) rediscovered the love of a Community Hall last April at SSR. I also made a couple of little friends who adopted Grandpa Mohawk and I over a game of giant jenga.
Things we did included: ceramics (there's a fee for the piece you pick to paint, ranges about $10-$30), made beaded keycard holders, played ping pong, PS2, etc. They also have a big screen TV and home theatre setup. In the day you're likely to see the kids channels on but they also stream the big sports games. (Unlike the rooms, the CH gets Fox Sports and other channels for the big games and American Idol.)
There's a schedule included in your Welcome Home booklet with activities, also one at the CH. Usualy the staff is hosting activities all over the complex as they are also in charge of the pools. So you may see them hosting bingo poolside or running the movie night after the lifeguards leave. Or else they do tie dye in the CH or have scavenger contests.
It is a very welcoming place to just wander in and play for a bit. Made a good mid-day retreat for Grandpa Mohawk when he was too hot to stand sitting by the pool. I just wanted to work there. Staff is great and it felt like camp to me.
