We were there the first week of Nov. last year and loved it so much we are planning to go back.
We collected FP - but didn't use them. We came home with a bunch. The longest we waited was 30 ish minutes for TSMM - but everything else was 5-10, including Space and Screamin. The only ride we ever used FP for that whole week was Space.
Park hours are 10 am to 8 pm at DL and 10 am to 6 pm at DCA. Do NOT expect any parades, fireworks or evening shows to be running during the week. Also, IASW will be down for it's holiday overlay. HM will be up and running.
Halloween decorations will be coming down daily and Christmas decorations will be going up in their place - we loved seeing the Christmas and Halloween decos side by side.
It was so uncrowded that our DS 7 was able to ride Screamin 15 times in 3 days before we all got tired of riding it with him and told him NO MORE! It was a great trip and I highly recommend going that week as long as you include a weekend day or two so you can see some fireworks and parades if that is important to you.
