We are members of the JCC and love it. They've redesigned the children's center and aquatics center... plus the gym has all new equipment.
I recently posted this review for the J Swim Academy (which is AMAZING): http://tinyurl.com/hv6vdw9
The kids take swim lessons, I go upstairs and workout, and then we all grab lunch at the cafe. We are now getting ready to sign up the kids of basketball lessons too! The whole facility is great for everyone!!!
The locker rooms are really nice - including hot tubs and steam rooms. It's basically become our country club with everything we could need!
Love the J!
