Okay, if this helps anyone...crowds at Epcot yesterday weren't super high or super low, sort of in the middle, I think.
We got to Epcot about 8:15 a.m. and there were already a bunch of people in line for the gates in front of us. They let us in the park early at about 8:40 and everyone did the "mad dash" to Frozen. The posted wait time was 10 minutes at 8:50 when we arrived. We made it all the way to the row just before the boats themselves when the ride broke down. We waited in line for 15-20 minutes while they fixed the ride and then we were able to get on. By the time we got off the ride it was 9:30 and the posted wait time for the ride was already 55 minutes. It definitely pays to get to the parks BEFORE rope drop, especially knowing that they do often let you in early.
Additionally, for the PP, we didn't do the Anna & Elsa M&G because we had a FP we needed to make, but we passed it on our way out of Norway at about 9:40 and the posted wait time was 30 minutes already.
