We just went to our first MNSSHP and Food & Wine from Oct 29-Nov 7. For months before hand I was dreading the weather; we hate humid (and I was born and raised in Hawaii, go figure) and we had vowed to stay away from Florida between the months of June and October. But, I really wanted to spend my birthday, Halloween, at WDW and do the F&W so we just basically braced ourselves for how sticky and yucky it might be. All in all, I have to say the weather wasn't terrible while we were there. It rained on/off the first 2 days but held off for the MNSSHP on Halloween night and was great for the Nov 2nd party. MNSSHP was great and I would absolutely go back for it. The crowds weren't terrible, even on Halloween night (which was sold out). Our only complaint was that almost all of the MNSSHP merchandise was long gone by the time Halloween rolled around; I just dont understand why Disney doesn't keep a stash just for Halloween night, bust it out at the start of the party, and then once it's gone that night, it's gone. Anyway, you should definitely GO!!!!
