Last year, we did find MK nuts, and as such planned less time there this trip. We spent 2 half days, a.m. on 12/27 from 7:00-11:00 and midday on 12/30 from 10:00-1:00. We did not have to fight crowds in or out of the park. (Meaning I could comfortably push a stroller and walk at a regular pace without having to find a sneaky exit through the stores.) The street wasn't empty, but it wasn't shoulder to shoulder people, either. They had the back passage behind Main Street open on our exit on 12/30, but not the other times. I am used to traveling during peak times, and this felt less nuts to me than other peak times. We perhaps got lucky with where we were at specific times relative to others.
