in late october, and we enjoyed it very much: not very crowded, warm, but not hot weather. since its not too busy things close early, and there's not as much going on, but it a nice time to go. in fact, we'll be going again this year the 22 thru the 30! i do not know if its still true, but on our two previous trips there were many people from england in the parks, we had a good time meeting and talking with them. its a fall school break time for them. i am sure mk will be packed on the 31, but overall , this is one of our favorite times of the year to visit wdw.
