I booked the Mirage way back in early January, arrival 4/9. I was offered a comp Mirage Suite but was hoping to move up to tower or penthouse upon arrival. I was in a penthouse last trip and I hate to go down. I just checked their web site and they are sold out on the day I arrive. I would imagine that will severely lower my chances of getting anything good. I hate to be stuck on the 4th floor near the ice machine facing the dumpster even if it is free. Who would have thought they would be sold out on a Tuesday? They are open all the other days that week. Hope this is not a bad luck omen.
