When I lived in Las Vegas, the Venetian became my second home. Poker games are available en masse in Vegas, but it was hard to beat the selection and comfort of the Venetian room. WIth plenty of space, constant cocktail service, and a dealer staff that remembered you after your second visit, it was easy to always feel welcome within the walls.
Good comp rates and private parking for local regulars certainly wasn't hurting their cause. Neither were their very solid tournament schedules and structures... including the Deep Stacks Extravaganzas.
What really impressed me was the management's willingness to listen to the players. When they wanted to start spreading PLO or 7 or 8 game mixes, they were always open to finding a way to put it on the schedule, and get some cards up for players that were interested. Where other card rooms would put the rake first, Venetian took the time to make sure the players were heard.
