Was I at the same place??!! We were there Oct 13 - 15 and the longest we waited for anything, anywhere was 15 mins! Character greeting lines were long at times, though - but we weren't really doing characters.
Oct 13: AK: potential waits were Safari and Kali, but we had FP, so 5 - 10 min wait max. We did Kali twice at the end of the day.
Oct 14: MK for
MNSSHP: 4 p.m. to midnight - longest wait was 15 min for Peter Pan - that area was very crowded right around 8.30 p.m. as people were gathering for the fireworks. The mountains were all 5 min waits (no FP). We only trick or treated when the line wasn't too long. We did all the rides except Astro Orbiter, the stuff in Toontown (though we did get pics with Donald Duck at the end of the night!), Small World & Aladdin (closed). This was MNSSHP, which is obviously quite different from a regular park day. When we got there at 4 we didn't attempt rides - we walked around and looked at all the scenery that wouldn't be as good as after dark, like flowers, rustic theming in Adventureland and Frontierland etc. We also took the train around the park to get a feel for it. I got pics with Timon, Rafiki and Big Louie - waited maybe 10 - 15 mins for them. We watched the fireworks and the 10 p.m. parade as well. I was amazed at everything we got done, and for much cheaper than a regular day's entry!
Oct 15: Epcot: didn't get there til noon, but the lines for the F & W booths weren't really long til evening. Still, I never waited longer than 5 - 10 mins at the booths - most waits were more like 3 mins or less earlier in the day. HISTA was walk on, so were the WS rides. Yes it was a bit crowded, but I didn't find it really hampered what we did. The longest wait was actually to get hot chocolate right before Illuminations (it was chilly!) - I was in a line for almost 20 mins cause everyone else was cold and had the same idea! We didn't do FW except HISTA and Living Seas.
We really didn't find it too bad at all overall. Mind you, we were adults and not doing characters. I'd go again with those crowds any day, as long as MK was during MNSSHP! Sounds like MK was bad during the day on the non-MNSSHP days.
