We went in 2014. We didn't go to a park on Saturday, went to Epcot Sunday. Don't know what the crowd level said, but it wasn't bad. Waits were a little bit bigger for major attractions, but overall crowded feel walking through wasn't bad at all. They just started FP+ so we had those planned for what we wanted. We weren't there for rope drop, but maybe about a half hour later and the wait for TT was about 45 minutes. Things like Nemo and turtle talk were very little wait the whole day, spaceship earth wasn't too long. TT and Soarin both were near or over and hour and a half most the day.
MLK day we went to HS and it wasn't bad crowd feeling wise either. About a half hour after rope drop TSM was about an hour, RNR was about 40. Throughout the day though they were also near an hour to hour and a half. TOT about 40 minutes most the time, others not bad.
Tuesday (MK) wasn't bad, but Thursday and Friday (HS then MK) after MLK day got quite crowded. Both those days the crowds felt heavier. Seemed much more crowded walking through the parks. We thought it was odd that it was more crowded after the holiday weekend. Although, I didn't look at crowd calendars/recommended parks so maybe we just went to the right parks at first and wrong ones later (although, we weren't at anyone from EMH that I remember)
