Although TTW is quite expensive, the experience is worth the cost. I visited TTW during October, so the crowds were not as much of an issue for me as some previous reviews. The spa was quite busy and they do seem to rush you from place to place -- but thats just the way it is!! The private baths are well worth the $25 or so -- just be wary that sitting in a hot bath combined with Santa Fe altitude can take a toll on your body!! I almost passed out when I was through with my bath and felt nauscious for about 30 mins. Beware that some of the baths are clothing optional -- I definitely saw a few bare butts when I wasn't even trying to!!
My Nose to Toes treatment was heavenly -- dont fear the hot oil hair treatment -- it is worth it!! My mother had the Indo Asian treatment which I deemed to be a better "bang for the buck" over the Nose to Tose -- she had everything that I had and more for the same price.
We also had the Nightingale Facials -- wow. Definitely a must-do service!! The bird poop is a little gimmicky -- but this was one of the bext facials that I have every had. Thorough exfoliation and very personalized service.
Look into packages if you go -- call and ask -- they seem to have seasonal packages.
