Went there just two weeks ago with my brother on a day off from the parks. The kids liked the trampoline section and we did some laser tag, air hockey, and a few other games. A bit pricey, but isn't everything? We didn't do the car museum, but there appears to be a lot there.
We paid for the full day ($25) of pinball and played for about 3 hours or so. Most machines needed work. From stuck flippers, can't locate balls, roll overs and targets not working, Addams Family thing was inop and the volume was turned so high it was distorted. Very few games worked like they should. A few had tolerable issues you could deal with, but some had several issues making it unplayable. About the only good was Theatre of Magic seemed to work well. I don't know who the attendant was, but he said "if anything doesn't work, let me know". We did on the first couple of machines, but all he did is put a "out of order" flyer under the glass and shut it off. Not complaining about him, but I don't think he knew how to fix them or what to do. We quit reporting all the defects because there were so many.
I didn't count how many pins were there, but my guess would be around 60-70 with 15 or so being EM's. There were a few newer games, but most were shut off broke. Most games were 80s, 90s, which is my genre anyway. It was hit or miss with them and usually a miss. Lots of potential, but like others have said earlier, no mx program to speak of so it seems. Bummer! Unless you find a game you like that works and stick with it, I'm not sure it's worth it.
