We were at Epcot yesterday too! I actually thought it seemed pretty empty; we walked onto Living with the Land at about 1.30pm, then walked onto Nemo right after.
You just missed the crowds. We had a FP for Soarin at 12:20pm and got in there about 11:15am to ride Living With the Land and other rides before our Soarin FP. That's when it was as crazy as I reported.
MK was busy today, but we got everything done we wanted to get done. We missed rope drop when the express monorail broke down due to a door that wouldn't close. It was a 20 minute wait for them to repair the monorail.
On this trip i've learned: 1) The week after Thanksgiving is going to be a busy time, 2) Rope Drop is your friend, 3) FP are your best friends!
