Rooms are fantastic and have a lot of character and depth, they make use of the different areas and really maximize the square footage. Casino property is attractive and clean, very stylish. Food, like everywhere in Vegas is very expensive and that keeps the younger crowd away and the casino floor kind of empty. Sorry, but I want a $10 steak and egg special so I don’t feel bad when I gamble $200 or $300 on the slots. We tend to eat one or two expensive meal when we stay in Vegas, but not every single one. The pool complex is amazing, clean, and hip. Lots of beautiful people and the one place I don’t mind spending money on the food, THE BURGER was fantastic and I would recommend to anybody. Parking was free and easy. Check in was simple, friendly, and unencumbered. We plan to stay again as long as the deals remain budget conscious.

I had a hard time providing a 5 star as staff plus a huge part in a hotel obtaining 5 star remarks. As the property is 5 star status its staff needed to go through luxury training and how to make a guest feel special to gain all well rounded 5 star status.
