Played volleyball here a couple of times where we rented the courts out for a few hours. The staff is pretty relaxed and doesn't bother us much. Didn't really get to try the other cool things - bumper cars, laser tag, etc. but it seems pretty easy and not a lot of people while we were there (Sunday morning - early afternoon).
I'd recommend for any kids parties or for family friendly activities. I did hear the prices are expensive for the games though.
