Throughout the first 2-3 days of the event tables can be hard to come by during the day. Basically as the tourney winds down they need less tables and some open up. You shouldn't have an issue getting a table after 10pm. There are also a few tables.......12 or so down stairs that are coin op and basically being played 24hrs a day but it's not just for a quarter. They are all money tables, guys playing races or just single racks for 10-20-50-100 bucks. You just throw your name on a list. There's always 1 table with big action. You'll know which one by the crowd and side bets can get crazy. It's a great time just beware that these money tables bring some heavy hitters! Best advise is watch for a little while, and don't get caught upon the side bets. A lot these guys are friends and I would suspect they will throw a game if the money on the side is right. I know I would.
Two years ago, it was $10 to rent a table all night after midnight. Last year, the tables were free after midnight or the last league match, which every comes last.
You also have the tables in the pit, with games ranging from $5-$100, action to suit your wallet. Those tables are $.25 a game, winner stays on.
