I am staying in Vegas over Memorial Day weekend but didn't show any free rooms on Saturday night (always the most expensive day) this year on my mLife account. I booked for Sunday and Monday nights. Then this week, in the middle of my Vegas trip, I got a new offer for that same property that included Saturday so I called the VIP services line to change dates and book the new offer. They said they can't comp the 27th but can do the dates I already booked. I didn't want to tip them off to me having an offer that included Saturday, so I just ended the call and immediately booked online. Booking went fine, just paying resort fees those nights and have a confirmation number. Any chance they bump me? Think the guy may have cancelled that offer if I mentioned it? It was weird, so I was just curious. People here often say you get better offers by calling, which wasn't the case this time.
