I haven't tried it yet, it's a significant investment when you consider everything. I was in a room in Pennsylvania that had it. The kids seemed to love it. We have a bowling alley in the area that does cosmic bowling and they do a terrific business on the nights they run it.
It is something I've been considering and will be interested in what others have to say about it. I think most of us have to shake things up a bit. Poker is eating our lunch!
