The Revive Spa at the JW Marriott Desert Ridge is a gorgeous and relaxing place. The facilities are as to be expected of a high-end resort. My only complaint is that the massage room started out much too cold for me. A couple of my co-workers had the same complaint.
The star of this spa, though, is the spa bistro. One of my female co-workers and I managed to convince a couple of the guys to join us for breakfast at the bistro. They were worried it would be too "girly," but once we sat down by the lovely pool in the lovely sunshine and were served our lovely food (fruit smoothies, whole grain waffles with goji berries, omelettes, granola and fruit parfaits), even the boys were in heaven. It was such a peaceful respite from the rest of the chaotic conference going on at the time.
Oh, but actually the true stars of this spa are the resident owls that watch over you from the palm trees! They are the coolest creatures and you can get awesome pictures of them if you have a zoom lens! Just don't sit on the lounge chairs directly beneath them...
