It's a great place for playdates (my little one is 7). Membership is reasonable, especially if you visit a few times per year. They change the exhibits and add live events and shows frequently enough that coming back is worthwhile. Membership includes free guest passes, free movies, discounts, blah, blah, which are great for playdates.
Parking pricing sucks now that it's managed by Diamond. Diamond is a fine parking company, but their pricing is outrageous.
