We just got back from 2 days at WDW. The crowds were not bad. We did MK on Saturday, from opening until 2 PM, and went on everything we wanted, using basic strategy and fastpass. We didn't wait more than 5 minutes for anything. We went to Epcot Saturday evening, arriving after 5 PM, and were able to fastpass Mission Space for a half hour later, and then we were able to fastpass Test Track. (Fastpasses are usually gone when we arrive in the late afternoon, so this was a surprise.)
We went to AK on Sunday. We went to DinoLand first, because DS was begging to go to the Boneyard. After that, we walked onto Triceratop Spin and Primeval Whirl with no wait. (DinoLand was empty, probably because Dinosaur was closed.) Then headed over to FOLK, and walked in right as the show was starting, without ever standing in line. After that we had an early lunch at Pizzafari, and then headed over to Africa. This was the one place we encountered crowds that were a little uncomfortable for us, but we expected that because we were there at noon. We grabbed fastpasses for the safari, and went on the train to Rafiki's Planet Watch. When we went back to KS to use our fastpasses, the fastpass line was longer than we had ever seen it, but almost immediately, DS announced he had to go to the bathroom, so we left. DH really wanted to go on KS, so after DS went to the bathroom, we returned and discovered the fastpass line was very short. Ten minutes can make a big difference.
We didn't go to Disney Studios this time, but I would guess it wasn't too crowded either.
Hope you have a great trip!
