Forbes Travel Guide ranks many of the better spas, resorts and restaurants. Usually the spas are at resorts. You can find their spa rankings here: http://www.startle.com/drilldown/business/Spa ... there are a small # of 5* spas, including the Broadmoor in Colorado (closest to you). Most of the 5*'s will be at expensive resorts like the Broadmoor.

Since you want good weather in the winter I'm assuming you want some place warm and fairly close, which implies California or Arizona or Nevada? California and Vegas each has four 5* spas listed. I've worked out at the fitness centers at the Encore (Vegas) and Grand del Mar (San Diego) close to the spas, for sure these are nice resorts. For sure not cheap ...

Prices are a lot more friendly at the four star properties. There are four listed in Colorado, though I'm guessing you want something warmer? Arizona has seven 4* spas listed (and great weather in February), the only one I'm familiar with is the Aji since my wife goes there 2-3 times a year (usually as a gift from me) and we dine at the 5* restaurant on that property often.

I said fare. I pack one carry on bag that will fit under the seat in front of me and pack 4 string cheese sticks. I'll share a $2 can of soda with my wife. I'll take any seat they want to assign me in the cattle car.

DEN - PHX $88 each way, all in as of now. Could drop with their famous sales. Expect sales before Christmas. Sign up for DING! on southwest.com for great fares.

Like lots of ocean with my spa so not a fan of AZ.

Really are at the very beginning of planning so don't necessary have a budget (probably not 5 star but 4 star rates would be okay). Decent weather would mean a decent chance of sun and 50's and up would be fine. Not interested in Hawaii or Caribbean because we would only do 3-4 days. I checked on a place in Oregon and they said usually the weather is windy and rainy, that doesn' appeal to me. Trust me, I know we are not guaranteed good weather but certainly don't need to go some place where the odds are that the weather will be rainy and windy. Arizona (Sedona, Phoenix, Scottsdale), New Mexico, and Southern California are all appealing.

Spas here in NM would most likely be in Albuquerque, Santa Fe or Taos, none of which will meet your weather requirements. Perfect in June - mid November, but February will be cold and good chance of snow.

Check out spas in Southern California, Arizona, mid to South Texas and Florida - generally mild weather in those places during February and you can probably reach any of them in under 3 hours of flying time.

tomfuller: I didn't say anyone needed to use all of those "services" (and that was only a few of the possible fees) - but everyone does need to book -- $17 pp. And if they need to gate check that carry on . . $35 a pop. Plus most of the fees are "opt outs", not "I agree's" so if you don't notice the opt out check box you are charged. Give me sweet/simple Southwest any time. But whatever floats your boat.

tidy: There are some lovely spas in the Napa/Sonoma area easily reached from OAK/SFO/SMF. The weather might or might not be great but the food and such can't be beat really.
