If you can get a good deal under $100 during the week, I'd say go for it if you want a smoke-free place without a casino (connects to MGM Grand -- it's a pretty long walk though).
Rooms are very large with kitchenette, very nice. Comfy beds, with feather pillows- I was terribly allergic too. They promptly brought me up down-like polyester pillows and these were the most comfy pillows ever!
Bathroom is huge with a shower and a jacuzzi tub.
Gym is okay, the pools were closed.. As were a good portion of the restaurants on a Monday night in December. Guess that's the problem with going off-season. Wasn't too happy that although you don't get to use all of the features of the resort, you still pay the full resort fee!
