This year will be our third trip on the week after Thanksgiving.
We arrive Saturday morning after Thanksgiving and the weekend is still a bit busy with 45 - 60 minute waits at most of the major attractions. But Monday through Friday of that week the past 2 years the parks are all virtually deserted. Mid day waits can be 30 minutes, but anything early in the morning or the last couple of hours in the evening are 5 - 10 minute waits at most.
The best part is your not bumping shoulders trying to walk around the park, your PS times at the restarants are always ready when you show up, you never have to scramble for a table at any of the counter service restaurants, you're not 5 deep trying to see a parade. We get curbside seating 5 minutes before the parades start. And the kids walk right up to characters for pictures and autographs without a wait.
We showed up at AK for the rope drop and went to Kilimanjaro first and walked right on without a wait. Animals everywhere with the cool morning temps in the 50's.
At MGM it's a straight walk all the way to the basement elevators at TOT, and when you get done there, it's a straight walk right into the pre-show area of RnR with Aerosmith.
Waits at Epcot for Soarin were about 15 minutes, and that or less at TT and MS.
I remember waiting about 10 minutes at MK for Buzz Lightyear, then doing SM by just walking right in without a wait. I don't think I ever saw anyone in a Fast pass line during the week.
Getting to the parks in the morning from your resort using the buses is a cinch, you get right on, sit up near the driver and on your way in just a few minutes. Same at night when the park closes, get right on without a wait, the cue lines are always empty. Get back to the room and ready for a dip in the pool? Even in November temps hit the 80's, yet the pool at night will only have a dozen guests or less.
You can enjoy leisurely strolls through the park, walk right onto the rides, get upfront seating in all the shows, and still see everything without having to run somewhere just to stand in line for an hour.
I know most people have to go during the summer when kids are out of school, but I can't imagine having to deal with the heat and crowds that most of you say you deal with at that time of year. My money doesn't come easy either and I would never think of spending it at Disney at any other time of year.
I've seens the frustration expressed in other threads from guest having to deal with rude, hot and fatigued people when the parks are packed and can say I've never had to experiance any of that by going when the parks are not crowded.
