My son says yes (I didn't remember) although he didn't play on it once.

Have him bring his own ball so he won't have to wait in line to check one in and out at the purser's desk. Same goes for ping pong balls and paddles, if he's interested. If it's like the one on the Conquest, it's half court (or so) and there's no water fountain up there. Gets very HOT! My 17 year old practically lived up there during the cruise.
Sonny..........shouldn't be a problem finding others to play 3 on 3 with. There always seemed to be a group on the court (mostly men and older teens) and "teams" ready to play the winner sitting on the sides. Have fun! Bring H2O!!!!
