DH and I have been twice. Once when we were mid-30's and once late-30's. We went with our boys, but we would have gone anyway. I was really bummed last time when we had to go because it was time to get the boys to sleep! lol We both enjoy it.
I am a rollercoaster chicken. However, I LOVED the build your own rollercoaster simulator. All the excitement without the heights!
I really enjoy getting to play my favorite games from yesteryear. I loved Centipede! I'm so bad at it now! lol Anyway, they have a lot of the old games (Centipede, Millipede, Qbert, Pacman, Astroids, King's Lair, etc...) The only complaint I have is that some of them don't work very well. Given that they are 30 years old, I guess it is probably hard to keep them up.
I can't even begin to talk about all the other games and simulators. It is amazing. That being said, if you don't like video games, there is no reason to go.
Enjoy!
