A few weeks ago I booked 3 nights at the Mirage under a promo that I found online. Now I see that a Comp Room Bonus is available for my final night. I called the Mirage reservation desk before I did anything. I asked if I should book the MyVegas night then call to cancel the reservation for my 3rd night. She said that I can not use a MyVegas room on consecutive nights with a reservation made on any promotion. (The promo is 20% off and $25 dining credit.) I asked if this was listed in the terms and conditions of the promo I booked under, the terms and conditions of MyVegas or both. She couldn't answer that but did say that they "just received a memo about this a few days ago". I asked her what would stop me from booking the MyVegas night then calling back to cancel the third night. She said that I wouldn't be able to book the MyVegas because they would see my reservation in the system already. I asked her what if I had booked the MyVegas room first, how would I handle the other two nights. She said that I would have to pay rack rate. Is this true? Any advice on what I could or should do? Anyone run into this before?
