No budget constraints.

As I said, we wouldn't be camping this trip. I don't think we want to
be in a very desolate, deserted location. I will check out the 4
corners area.

Thanks.

Check out Salida, CO about 100 mile south west of Denver (2.5 hour
drive). We're low at 7000 feet but we're surrounded by mountains
with lots of very dark observing spots within 10 miles. We have a good
approximation of civilization in town with lots of things to do when the
sun's up, a few nice restaurants, shops, B&Bs etc. Observing doesn't
get much better than in September, with conditions warmer than winter,
calmer and dryer air than mid-summer.
Good luck, see:
