We did May 31 to June 7 last year and it wasnt as bad as I expected, and we did parks based upon ADR and not on recommended parks. HS was bad due to SWW, AK wasnt ever bad, and MK got pretty busy late morning until Wishes, then got very light. Epcot was surprisingly busy early for us, but we snagged a walk up patio table at Rose and Crown at 730 to 8 for illuminations so it seemed to thin out as the day drug on. I never checked what levels the parks were, but guessing at least 6 or 7, with likely 8 or 9 Friday and Saturday.
7DMT was never below 80 or 90 min and A & E was 3 to 5 hours, but nearly all other MK was never above 60 for us.
HS headliners generally 90 min or more, but ToT was frequently under 1 hour.
EPCOT was packed as I mentioned early, but we had FP two different days, and did half days only, so didnt really watch SB times, plus did single rider at TT a few times. I do think TT was 45 to 90, and Soarin was always 1 to 2 hours.
AK we did safari FP and EE we didnt need it due to 20 min SB plus single rider.
Edit: Should mention despite SWW, ST was never above 30, my son and i rode it 7 times, usually in a 10 minute queue.
