My brother and his wife and myself and my wife are going to be sharing a comped room at Bally's during the first week of March. They will arrive in Vegas about 6 hours ahead of us and plan on checking in before we get there because the room is under his name. When I arrive I was going to try and have our room upgrade to a bigger room or even a suite perhaps for free. I was wondering if anyone had any experience trying to upgrade a room after it had already been checked in to? And also should I even be trying to have a comped room upgraded? Or is that an unwritten rule that your getting this for free so be happy?
