I went for Saturday last year and has a blast. I can easily say it was the best pinball playing experience I've ever had. So many games to choose from, rarely any wait time and everything was working perfectly. The few instances that a game went down, techs were on the job immediately. The only bummer was that I didn't have more time to play everything. Solution - go for 2 or 3 days this year.
I really like the idea of adding headphone jacks to some games. I'll definitely take advantage of that!
