Haven't been there in a couple months, so things may have changed, but it used to be that they opened that 'eastern' pit near the poker room, mixx and wolfgang puck's at noon. Somedays they only open all the tables including blackjack and somedays they open everything but blackjack. I think the weekdays, they don't open blackjack in that area, but Fri, Sat, Sun they open everything. They also open a few additional tables in the $10 blackjack pit on the main floor and additional $25 tables on the main floor at noon, so that is a good time to play as everything thins out and for an hour or two you can even table hop.
