My husband and I spent a night at Ten Thousand Waves in September 2012. It was his first time ever at a spa but I have traveled to destination spas for several years. It seemed a little disorganized upon check in but that may just be because the other spa I travel to regularly is absolutely top notch and I probably shouldn't compare to it. The rooms at Ten Thousand Waves are absolutely gorgeous - we stayed in Rising Moon and it was perfect inside, but it sits right next to the highway and was loud. If you want quiet and relaxing, I highly recommend a room on the other side of the resort. However, I can't see how any of the rooms would be far enough from the highway that they wouldn't have some highway noise. That was the main negative of the stay. We both had massages and they were good. Mine was in a pagoda in the forest with open windows so I could feel a breeze and hear birds singing. Unfortunately I also heard the cars on the highway :( We reserved a private couples hot bath that night at 8:45. We had the Waterfall tub which was great -- LOVED IT. It's a big tub, more than we probably needed for two people, but would be good for larger groups. We also had a cold dip with the waterfall which was nice for cooling down after sitting in the hot tub for awhile. It's nice that these tubs are very private - they are fenced areas and gated with a lock so you can go in your swimsuit or not without being worried. We were there on a full moon so it was incredible sitting in the tub under a bright moon-filled sky.
Also, be aware that there is very little in the way of food on the property. There are a few grab & go sandwiches, etc., but for meals you will need to go into town or order in. There is a delivery service that works with about 10-12 different restaurants and brings it right to your room. We had originally planned to go into Santa Fe to eat dinner but after relaxing with a massage we just ordered in and really enjoyed that. The office has DVDs and we watched a movie and ate dinner in the room before our tubbing time.
Loved the experience, just wish it would have been a more serene location, especially for the $$.
