We enjoy Durango, and have stayed as AspenRose a few times. Lovely campground, watch the morning Silverton train, which is a great family experience. Day trips to Masa Verde. My daughter took her RV and based at Mesa Verde this summer and said the KOA there was excellent. A day trip to Farmington New Mexico is also nice, lots of Indian museums, and a nice casino. Another choice is Estes Park, beautiful, fantastic, high elevation makes it hard to breath for the first day or two...not so much for the kids, but it was well worth it. You really can't go wrong in Colorado.
