Stay away on rainy days. We thought this would be perfect for a day it rained, as apparently did everybody else that day. There was a lengthy line just to get in and it was VERY crowded inside.
Of the six of us (me, DH, DS17, DS11, DS6 and DD19) only the 11yo even likes it enough to bother going back, really. I usually play a game or two and get bored, which is the case for most of the family. We went when we had PAPs, but I don't see us every actually paying to get in there.
JMHO, of course.
