I can't speculate that far ahead, but I can tell you this...
We spent a day at a local "Adventure Park" where they have Alpine slides, a bungee trampoline, rock climbing wall, etc. Everyone is required to wear a mask all day. We had a great time and no one really cared about the masks. I believe that was because we were outdoors having fun and we were able to take mask breaks. We were also on a mountain, where the temperature is cooler; I think it was mid 70s, whereas at the lower elevation where we live it was mid 80s.
With that said, I don't feel like a mask would physically be a problem at DLR in November. Anaheim temps in November are historically in the 60s-70s, so I don't think it would be uncomfortable. You'll be doing fun things and able to take mask breaks, both of which make it bearable. At that point, I think it's really more about whether or not you're willing to have your first trip be one where masks are required, and where you may have a more limited experience due to certain attractions or shows being closed.
PS - if you were going in the summer, I'd say forget it. I spent 4 hours in a mask outside on concrete the other day. It was 90+ and I was miserable. The temperature of the day makes a HUGE difference in whether or not the mask is bearable!
