We went in mid-October last year. Although I don't remember exactly when I bought my tickets, I do know that I got them long before it was time to make my ADR's. We'll be driving from IN the same weekend also. From what I could find from my searches, there should be a party on the 15th and the 19th. We went on a Sunday last year. We had a great time. The lines were way shorter than any other time we went including EMH, which for us was a waste of time. This year we're going just to MNSSHP. We're staying at Nick Hotel, doing the cheap Universal Studios deal, and just hanging out and shopping. We still have some days left-over from our trip last year so we might do more days at WDW but last year we went to MNSSHP our first night and although we had fun, the longer lines were a let-down after MNSSHP.
