I had a stay-cation here last week. Went to see a show at House of Blues, eat, drink and not worry about getting home after a drunken night or work the next day. Originally I just asked for a basic room at Mandalay Bay but since my date and I were locals they upgraded us to The Hotel. The room was nice. I liked the mirrored closet doors and entertainment area and the large tub. The bed was comfortable. I really liked that the Hotel even though its attached to Mandalay Bay with a hallway is quiet and not much walk through traffic in the lobby and common areas.
The employees I encountered were all very friendly when I did ask something or need anything. The employees mostly had very robotic and somewhat standoffish looks but once they were approached they were very helpful and friendly.
The only problem with The Hotel has to do with how paper thin the walls are. Every time a person closes their door anywhere within 15 rooms of you or has a conversation in the hall in that range, you can hear it like your own room. I am dead to the world when I sleep but in the morning I could hear every person that was up at 6am closing (but sounds like slamming) their doors. The Hotel, get some better insulation, sound buffering carpet and walls and you will have a solid 4 stars not rounded up. This makes me lean a lot closer to 3 stars but it was a very nice stay so it gets 4.
