My memory of the place is very vague and also from a few years back, when our son was competing there. There was a pool room or two within walking distance, in a nearby mall. One was a restaurant with only a few tables. The other one had a lot more tables and was pretty nice. We went with the boys there. I believe it was open to all ages. (It seems like that mall was right across the street from the convention center.)
At any rate, when you get there, it's a beautiful place and the people are nice. Ask around when you get there and you'll quickly learn where to find a pool room.
You said you're going, but didn't specify if you'll be competing. Does that mean you're going with someone else who will be competing?
