Mandalay Bay is a beautiful hotel/casio with a nice selection of restaurants and very cool rooms. We stayed in the newly furnished \"Gold Class\" suites (all the suites may be newly furnished by now, but when we checked in it didn't seem like they were).  The room is comfortable and has a very modern aesthetic. \n\nA couple of small things are keeping this from a four star review. \n\n1.) The pool is beautiful but when we were there in July it was so incredibly crowded that it was difficult to find pool side seats. The lazy river was so full of people trudging along that it ceased to be both lazy and a river; it was more like rush hour on the way to a factory job. Also, the pool doesn't have umbrellas available for you unless you pay for a cabana, and we didn't choose this option (it's way too pricey for just two!). The other thing that such a nice pool brings is a large number of kids, so keep this in mind if you choose Mandalay Bay in the summer.\n\n2.) I had a pair of earrings stolen from the room. I know, I know, keep them in the safe. It's my fault for leaving them out, but still ...  After I called to report them missing, they did send up a very nice and helpful security person, but there was really nothing he could do. He may have spoken to housekeeping about this, however, because it was difficult for us to get any housekeeping after the incident. It was like we were being punished for reporting the earrings missing.
