Best Spas?

Okay, so I am feeling like a spa slut b/c I've been to The Allison Inn and Spa in Oregon, Miraval Spa in Tucson, and The (I) Spa in SF in the past month. But I'm always looking for new spas, plus my masseuse is traveling for 6 months so, I'll be in need of a new spa until she returns.

The (I) Spa in SOMA had an open house this week which was great. I got a mini massage for free + cocktails and h'or deurves. Plus if you booked a treatment that night for the future, you got $50 off. Worth it!

I've also been to Nob Hill Spa - which as a luxurious sitting area, snacks, pool, the whole 9 yards - you really feel like you are being pampered. And I've been to TruSpa a few times (downtown/NorthBeach/Chinatown area) - also great facials there,but not a great sitting room.

I've also been to the Claremont Spa in Berkely - although it's been about 5 years and the Ritz Carlton spa in Half Moon Bay - also very nice, but not one you can relax and spend all day in.

Anyone been to Elizabeth Arden's Red Door spa? Can anyone recommend any others? I feel like I am on a journey and I'd like your help.
Thanks!
