I was told that if we spent money at the property, ie.. restaurant and bar, our destination fee would be refunded. That was not the case. $25 per day per room plus $1.63 taxes on that fee!! We spent $126.00 the first day at the rooftop restaurant and they would only reimburse $25 for one room and I had paid for 2rooms. And you have to spend $25 dollars, specifically assigned to each room each day?!? Which was not clear in their policy.

Hotel was great. Clean and the room was comfortable. Front desk staff was very friendly. Breakfast in the restaurant downstairs could have been skipped, not really worth the price.
