I am a CET Diamond. A low diamond I admit but I have always been able to get room comps in Vegas. That seems to have disappeared overnight. Yesterday all mid-week and most weekends at mid-tiers were totally comped through Fall and Winter, now I can't get a free room at Rio on a Wednesday in December. Definitely not for lack of play. I was in Vegas this month and earned 10k Tier credits.. New policy? System glitch? Anyone have any idea?
