Purely anecdotal, but it LOOKS like crowds picked up pretty heavily in the second half of last week, at least relative to where they were ~12/18 to Christmas. Didn’t see anything headline-worthy insane like in years past, but a couple big rides started flirting with 3 hours.
Interestingly enough, Magic Kingdom was the only park to really look average all week. Not sure if that’s because we’ve gotten used to it being jam packed all the time, they’re truly capping attendance with the reservation system, OR (and this one’s a little more out there), it’s the more quintessential tourist park and travel delays kept this holiday more local-heavy skewing guests toward the parks with newer rides (or in Epcot’s case, more alcohol).
