Sharing hours among roomates to get poker room rate

[profitman]

Which casinos let you share hours among roommates to qualify for the poker room rates in Vegas? I'm going to Vegas on the October 12th weekend and I'd like to stay at Caesars since they have the Caesars Classic tournies starting that weekend. Allvegaspoker.com says Caesars requires 8 hours of play. I'm wondering if I can split the time with a roommate. If not, what other hotels allow you to split time. I think venetian does.
