Oh, where to begin with Mandalay Bay. I have stayed in both regular and nicer rooms. The rooms have been newly remodeled in the last 2 years or so possibly 3 years. Very contemporary and very modern looking.
The beds are great and comfy always the first thing I look for. The bathrooms are perfectly situated too. The pool is awesome and great to lay on a chair hung over the whole day and people watch. I love going when its cloudy because there is less people there. The wave pool is fun but you cant go to far out into it. The round pool, not sure what that's called. The one that is constantly going in a circle is usually full so I have only done that one once.
Do not order room service. I don't mind waiting 45 minutes for my food but I expect it to show up hot. Not have it sitting out for, judging from the temperature, 30 out of the 45 minutes. They could give a crap that I complained.
All in all my husband and I really enjoy going to Mandalay Bay. Its conveniently located to access other hotels and the shopping in the middle is fun.
