Yeah, the wait for the low limit games is terrible. I've pretty much stopped playing there because I hate the wait, and the rake also (second worst rake in the country). It did improve since they took the bad beat jackpot off the 2/4 tables.
If the waiting time has improved since they upgraded the poker room, I haven't noticed. They have started a really good thing, I hope they will soon improve/expand their staff to complement the expansion. You shouldn't have to wait an hour to play on a friday when there are tables open.
