First of all, I'm not a big fan of Marriott. It seems that every time I stay at one there are clear areas that need to be improved. They really need to step up their game when compared to Hilton.
The most important part of this place is where you will be spending the most time; the bed. It's extremely hard (or firm if you prefer). I was able to sleep on it but it was much too hard. If you are used to memory foam or a pillow top you may not be able to sleep on it.
The hotel is in desperate need of an update. The carpets are old and it just feels a bit run down.
On the positive side, they have a decent free breakfast, it's inexpensive, and fairly accessible from the strip and airport. Plus they have a free shuttle.
If I can get a free room with points then I will stay here again but otherwise I wouldn't waste my money.
