Also very southwestern "artsy". Smaller experience than Scottsdale (which is great too), although Sedona's Oak Creek Canyon has a beautiful treeline among the creek. If you like Kokopelli's (sp?) and the like, and don't mind taking a drive in your RV, I enjoyed it. My Sedona trip has decorated my yard and house. My husband and I only planned to stay for 2 nights...turned into 5.
I've been there. It is beautiful. The town has too many artsy fartsy hippies and the like for my tastes!
