Planning to take my family visiting Colorado across the Million Dollar Highway. Is it still as scenic with snow capped mountains in July? Is it worth it this time of the year?

I'm planning to spend my birthday this November in Colorado. We will be arriving Denver airport 11/18 at 9:40pm and will be there until Nov. 24 at 5:30pm. Places we are interested in are Estes Park/ RMNP (not sure about this one because of fire), Durango (for Winter Train), Ouray/ Telluride (Ski) and Glenwood Springs (for Yampah Spa). Is this too much to do from 11/18-11/24? This is our first time visiting Colorado and I am not a seasoned winter condition driver. I do have reservations for an all wheel SUV. 1. Should I go straight to Estes Park the night we arrive (Nov. 18)? Is the road safe to drive? 2. I would like to do the train in Durango, but is hesitant because of having to go through the Million Dollar Hwy. How is weather up there during late Nov? I was also wondering if Durango to Ouray via car vs. Durango Train has the same views or different experience? 3. If I had to cancel any of my destinations d/t weather or time restrictions, which one should I cancel? (Estes/ RMNP, Durango, Ouray, Telluride) Any recommendations on closer alternatives? 4. I wanted to keep Glenwood springs because It's the only Spa I can find that's interesting and provide scrub/ massages. Any recommendations? So far our itinerary is Denver> Estes/ RMNP> Durango> Ouray/ Telluride> Glenwood Spring> Denver. I think I may have a case of FOMO! LOL!!! But I'm open to any suggestions and safety advice y'all might have. Thanks in advance!!
