I will be in Denver in a couple weeks. Unfortunately due to time constraints and the absurd price of sleepers, I'm flying, but would like to do a day trip west of Denver. I've already done CHI-DEN. Based on the OTP and the numer of things to explore in the surrounding area, especially in case of a late train, what is best: Winter Park, Granby, or Glenwood Springs? I would only be able to do Glenwood Springs if #6 is very delayed. I'm willing to make a last-minute ticket change in case of an extremely late train.
