We went last week of August this year, hours were reduced but crowds weren't that bad. Most AM we were in Epcot all by ourselves (we stayed at Beach Club), really only felt the crowds at MK and especially Fantasyland. My kids are older though and not into MK all that much. The weather was overcast, I think we lucked out, only 2 out of 9 days felt really hot, and we do not like heat. We enjoyed it, would do it again. In fact DH and I went again in October for the Food & Wine Festival and it was more crowded and just as hot. We saw a husband and wife walking around Epcot and her DH goes - I'll never come in August you would have to be crazy. I of course had to pipe in, that we were there end of August and it was less crowded and not any hotter. His wife goes -- see I told you, he says -- she is lying, she says -- why would she lie? They then proceed to argue all the way out the park, dh and I were hysterical laughing.
