The property was off the main strip but it was still in a decent area. The staff was awesome! Wish there was more places to eat in the area and there was early check in available.

We always have an amazing time here! While the halls of the hotel could use a facelift, the lobby and service makes up for it ! Amazing quality of drinks, food and entertainment! And being only 5 minutes from the airport, makes it a wonderful option for a quick trip, with everything you could want. Love it here!
