I suppose my recommendation would be to repeat the San Juans once more for West Coast Camp, but running from a different base to mix things up: Ouray or Ridgway, probably.

One could then adequately plan for somewhere else in Colorado for the National Camp event. Gunnison, Fairplay, and Buena Vista come quickly to mind. Perhaps best, though, would be Georgetown, which is easy to access just out of Denver on the interstate, but is also close to a wide range of terrific trails. I do think most folks would enjoy something like that more than a private park.
