I would like to know if the weather in Santa Fe during the week of Thanksgiving is still nice? We would be driving down from Colorado Springs. Are there restaurants around that would serve Thanksgiving dinner? What about kids activities (our daughter is 10, son is 2). We would be staying at the Villas of Santa Fe through an II trade. Thanks!
Our weather is similar to what you get in CS, except that your winter is a little longer and slightly colder. Absent some significant variation from average, expect highs in the 40's/50's and lows in the teens/20's, with very little precipitation. Perhaps your biggest weather issue might be to keep an eye on what the weather is like in the Raton Pass, assuming you are coming down I-25.
As for restaurants serving TG dinner, pretty much all of the nicer places do that since there are so many tourists in town that weekend. The Villas of SF is close to the plaza area and the many restaurants located there, so your choices will be many. If you deciede to eat out that day, you might want to look around on your very first day and get a reservation somewhere while they are available. Maybe check out some places online like Coyote Cafe, Pasqual's, Inn of the Anasazi, La Casa Sena, Ristra, Santacafe, The Olde House at the Eldorado - they are all nice and close to your unit (maybe others will add to or subtract from this list based upon actual experience on TG day). Or for more casual places, look at Santa Fe Bar & Grill - walking distance and Zia Diner. Or you could always just order the complete meal from Albertson's, which is less than a block from where you are staying.
As for kids activities - that is a tough one. Unfortunatley, SF isn't a great kid destination. There is a Children's Museum on Old Pecos Trail (5 min drive). You could go visit the Anasazi cave dwellings at Bandelier National Monument (40 min drive). You could drive up to Taos and see the pueblo and the Rio Grande Gorge (75 min drive). Actually, you could go home through Taos without adding a ton of time to the drive. You could go down to Albuquerque and ride the tram up Sandia mountain. Or go to the Audobon Center at the top of Uppper Canyon Road (5 min drive). They have some great stuff for kids. Plus there are many easy hikes in the foothills around town - look up the Dale Balle trail system.
I hope that helps a little. Enjoy your trip!
