Man, I have great memories of Glenwood Springs, from my childhood. As someone mentioned earlier, it might be tough to stay there more than a day, or so. But it is beautiful. And the hot springs this time of year is pretty cool.
Another thing I've always wanted to do is to rent one of the many cabins in Colorado. It would be secluded, and probably pretty reasonable. The Denver Post ran an article about a year ago about private cabins around Colorado that almost made me salivate. There were some absolutely incredible properties. Sorry, I tried to find the article for you, but I didn't have much luck. But if you Google "Colorado cabin rental," I think you'd find some pretty incredible stuff.
Also, if you get near Dove Valley, Broncos headquarters is always a fun visit!
