Yeah they are all in tip top shape and work great. I was there last night. It's definitely a very cool thing.
Did you play America's Most Haunted? I was super excited for it...but it was a huge let down. The "bridge" ramp looks cool but doesn't work well. When you nail the shot, it just air balls and misses the landing. The shot up the middle (to the right of the ghost) rarely makes it, and when comes back down it goes SDTM. Bummer.
