Probably deserves 3.5 stars.
Tends to be a mid-priced hotel on the strip and is very nice. The rooms are extremely comfortable and have fun memorabilia on the walls. The crowd is generally pretty young and trendy. I wouldn't take a family here, but would be a great place for a bachelor party.
The casino has a great vibe. It's similar to the Hard Rock, but bigger and with a better location. The Spice Market buffett is pretty decent, but I generally don't care for Vegas buffetts.
The pool is just ok.
