This is one of the Hotels that you can book for a free nights stay by having the Hilton Aspire card. In my case, I had saved up two years and stayed for two nights. And what a luxury. Not only is the hotel stay free, but you get a $50/day meal benefit that you can use at one of the restaurants for breakfast, Lunch, or dinner.
The grounds are amazing. There are three pools to choose from. And one of them has a 50 foot tall waterslide. There are several places to relax and sit and enjoy the ambiance. The Arizona Biltmore is similar to timeshares with the exception of most (if not all rooms) lacking in the kitchen facilities of a timeshare. The grounds and service were world class.
