I'm going to say yes. 2018 was the most crowded that I have ever seen Marathon Weekend (it was the Polar Vortex and I distinctly remember being bundled in a winter coat and wading through an unbelievable amount of people in AK. Marathon Weekend was January 4-7 that year.
And I just remembered I'm planning to do Dopey in 2023, so I'd have to deal with all those crowds instead of staying longer the week after. Ugh!
