Great link to a great article, randyi. I was fortunate enough to see the Paiza Club--my host at the Venetian was kind enough to give me an undeserved tour. The actual gambling area there is nice enough, but nothing spectacular--think most high limit private room and areas at the better places. The emphasis is on service, discreetness and exclusivity. They can sleep at the tables there if they want--have a sandwich flown in from Paris if they want, nothing is denied--in this place, truly "we can't..." means losing their business.
Great article on comps and insight into comps too. Thanks for posting.
