I was there shortly after it opened, and as a hotel it was great. You can walk out to a bunch of shops/restaurants as well.
I don't play poker but from what I saw it was a poker "area", not a room. The times I walked through they didn't have all the tables open, and players had to check in and be assigned a table. That may not be the case depending on when you go and how crowded it is. But the area wasn't that large.
