We went this year late morning on MLK day (after a few hours at AK in the AM). We found it manageable, but we also didn't try to ride anything mid day without FP. I don't exactly remember wait times but do think they were a long. I do remember thinking it felt crowded, but nothing major. FP lines were about 20 minutes or more for SE and TT which we felt was long.
We got there saw the acrobats in France, went to lunch at Tutto Italia, saw voices of liberty then the American film. Stopped on the way over towards our Nemo FP to see a little of the British band. Used our FP for Nemo, SE, then TT. Rode the boat ride in Mexico, then ate at San Angel Inn. Probably a little before 830 we got in line and rode MS then went and rode TT. Illuminations ended as we were getting off, so we were walking out with the crowds. It was a long day, but it went smooth. We got to do everything we wanted.
