Lou's got the right idea.... set it up as a prelude to the party. Use an aggressive blind structure and it can be ending around the time the party starts. And paying dealer's would be a lot cheaper than a rake by the casino. That 2-3 a hand adds up real quick.
Another idea is an On-Line tournament. The Rx. can contact any one of at least 10 on-line Poker sites. Lot's of people play for big money on-line, or you can play for fun. Just another idea to bring the Holdem players here at the Rx. together without a trip to Vegas.
If you like Texas Hold-em check out the Travel Channel tonight at 9PM Eastern. World Poker Tour Final from Costa Rica (Of all Places). They show play at the final table and the winner during a one hour show. On every Wednesday night from a different location, leading up to a grand final tounament in Vegas. Good show.
