I am going to be staying at Mirage using a MyVegas comp and I was wondering about how the pool worked. What I'd like to do is allow myself and three others access to the Mirage pool on the day I check out. I guess that brings about a few questions: 1) Do you simply need to show a Mirage key to gain access or are the keys scanned and must match a unique guest (basically, can I get extra keys from the front desk and let people use them to get into the pool with me)? 2) Does anyone know if there is a limit on the number of people staying in a MyVegas Comp Room? My backup plan would be to just add everyone to the room, but I didn't know if I'd be charged extra since the room is comped or how that might work. Thanks for your help.
