Fantastic! Great section for 7 and under. My kids were there for over 2 hours and still didn't want to leave. I read a couple reviews below, one said it was warm (maybe the ac wasn't working then because it felt fine on a 110 degree day) and the second was music (They had music playing but it was only an hour or so loop because I was hearing the repeats).
The place is nice and airy. Parents can sit and get a good view of their kids playing. My only suggestion would be to provide some arm chairs. Some of us parents are getting older and sitting at a picnic bench can be a lot on our backs.
