Got an out-of-the-blue phone call from a host at Cosmopolitan offering me two free weekend nights and a greatly reduced rate on a third night later this month. I stayed at Cosmo once two years ago, didn't gamble very much at all there because the table mins were so high. Haven't been back to Vegas since. I took him up on the offer and have the trip booked. The value of the room that weekend is outrageous, Saturday night is like $495 on the website. He said to contact him before I leave to see if my play garnered any additional comps. I can't envision that occurring. My worry is that they will try to stick me with part of the bill because I didn't gamble enough. Am I crazy for worrying about this?
