By the way, can you talk to my husband?
My kids are 3 and 1 and I have yet to be pampered like that.

5pairs, great idea. I hope you find just the right place!
For everyone talking about the "old days", if you are lucky enough to have your mother still with you, then send HER to a spa!! A belated thank you.
My mother is coming to visit us in Brussels in January and tops on our agenda is a long week-end at a luxury hotel in Baden-Baden, Germany. We'll be doing the thermal baths and she's already scheduled for a back massage (shh...don't tell, it's a surprise!)

Miraval, near Tucson. The weather should be perfect that time of year.

Interesting website. I'd personally pick Calif wine country.
