I'm not addicted to planning for this trip. I could quit anytime.....but I'm no quitter ;)
The Jedi doesn't like caves, and Nana couldn't do a 70 minute walking tour, but I have to make note of Glenwood Caverns anyway. Neither will we be taking a 90 minute tour of Redstone Castle, because that takes 90 minutes, and we're already driving 9 hours that day. Glenwood Springs is home to the world's largest hot springs pool, which is pretty cool (well, warm, technically), but again, time, and sulphur might be a deterrent there. However, the Two Rivers Park as a possible get out and stretch legs point in Glenwood Springs.
Colorado National Monument near Grand Junction. He found a dinner that we can hit before driving to the northwest park entrance.
