Upscale "glamping" can be had at Wolf Creek RV Park in Pagosa Springs, CO.

The Hot Springs is a short drive from the park, and it's a beautiful place to see, as well as soak weary bones. Here's a link to the Hot Springs (even if it says "Loading" in this link):
Hide the credit cards, as there's tons of shopping in unique shops around town. Don't miss Goodman's Department store - the original wooden floors from long ago creak when you walk on them, and there's a huge selection of western gear - you'll smell the leather when you walk in the front door. Say hi to Bob Goodman if he's there - the store's been in his family for over 100 years.
Take a ride up to the top of the Continental Divide on Wolf Creek Pass - worth the trip, and about 25 miles away. If you feel adventurous, right at the top there's a road on the north side that goes right up to the crest, and a great hiking trail from there. Passenger cars can make it pretty easily with just a little attention to the gravel road to miss the rough spots. Take a lunch - there's a picnic area there with restrooms.
On the way to Wolf Creek Pass at the base of the mountains is Treasure Falls, and a fairly easy hike up to the top of the trail leads you to the base of the falls. The valley floor comprises Bootjack Ranch, which just sold for over $50M. In my opinion, based on beauty alone, it should have sold for twice that.
Chimney Rock National Monument, on the west side of town, provides a fascinating insight to the ancient Anasazi life, complete with abandoned ruins and kivas (ceremonial rooms). Definitely worth seeing.
If you're old enough to remember Red Ryder, stop in and say hello to Fred Harmon at the Harmon Museum. Fred is the son of the author and artist of the same name who drew the series, and was a contemporary of Walt Disney. Fred also worked for CBS in New York, and was key in producing lots of shows you'll be familiar with, such as 60 Minutes - ask him about it. Fred's a great guy, and will happily tell you about life here in Pagosa "way back when", upon which Red Ryder's exploits are based.
That should last you a few days...and there's far more to do in the general area.
There's the Aztec Ruins in Aztec NM (just across the border south of Durango), also home to Anasazi ruins and the only completely restored ceremonial kiva - a beautiful thing to see. It's all within a few hundred feet of the entrance, and on level ground.
As others have mentioned, Mesa Verde is not to be missed. We've hiked the back country there dozens of times, and still see things we've missed.
Don't miss the Durango narrow gauge railroad either - take a ride to Silverton, CO, an old mining town where my relatives mined for silver - unfortunately, they didn't strike it rich, or anywhere close to it.
Hope that helps...
