I stayed New Years Day night and the following night for a two day getaway.
MGM Grand is a beautiful property, and the rooms are luxurious. The showers and bathrooms are new, modern, amazing.
Mystic is a quick 10 miles away.
The day spa is $15 on the weekdays. It has a nice lap pool, and sauna.
We tried Shrine. It is really trendy and Vegas-like inside, but it is really overpriced Chinese food.
Overall: the beds are great. It's a really relaxing getaway.
