I was there on Sunday morning, took wife and kids. I'm a little closer than you about 10 miles east of princeton. First time there, was really great. I played a lot of the older ones, but also many more modern like MM, which some guy was hogging for over an hour, Sopranos, AFM, TOM, DM, GNR, TZ, FH, Elvira, BK , IJ and a ton more. Had planned to stay an hour, but turned out to be three and easily could have been an entire day had it not been for tired kids. $20 for the day will hardly dent anyone's wallet. Highly recommend it, but go during off hours, when they open or during the week so it's less crowded.
