So we went to the 10/9 party and had a blast. We arrived right around 4:00pm and went through the special party entrance lines. After that we went through the bypass and got our bags and first bit of candy. We then had a fast pass to Space Mountain from 3:45-4:45. The normal wait for space mountain was really high. After that we met up with my brother in law/sister in law and their two kids. Went through the alley again with them and got a couple of pictures. Decided to split the one day memory maker with them. We then had a seven dwarfs mine train fast pass, so we went and did that while they headed to Dumbo. We met up with them and rode dumbo. Also looked at the party exclusive merchandise and I wasn't impressed.
Overall, I did not think it was that crowded. We were not interested in character meets, but all lines were long. We managed to ride the Little Mermaid Ride along with the others mentioned above before the parade and did some trick or treating, and a picture or two. We then found spots in frontierland on the side of the castle. While we were waiting for the parade (about 45 min), we took turns saving spot and going to get a picture in front of the castle. After parade, we made our way closer to the front of the castle for fireworks.
After fireworks, we did a few more pics and trick or treating and then our niece/nephew zonked out, so we parted ways and they headed out of the park. We passed POTC and the wait was still 40 min, so we made our way to Haunted Mansion and it was down to 10 min (was 40 before parade). After Haunted and pic in front of carriage, we went back to POTC and it was down to 10 min. After this we did trick or treating and made our way to tomorrowland. We boarded the people mover at 11:56 (one of my childhood favorites). Afterwards, we headed out and were back to our hotel by 1:00 am.
We did see the Oogie Boogie popcorn bucket at a kiosk near Gaston's. We got in line to get one because my husband wanted one, but by the time we got to the front he had changed his mind (as I asked what he was going to do with it when we got home lol). It was really easy to get one and there was only about 2-3 people ahead of us in line.
We also forgot to eat dinner so we grabbed a cinnamon roll at Gaston's. Oh my, that thing was awesome. I would def. get again but split between several (we split it between the 4 adults).
Overall, we had a blast and would definitely do it again. We did it in lieu of a 3rd day at the parks and I believe we got a lot more in than if we had done a day at the Magic Kingdom. We ended up with three bags full of candy, several cool pics with magic in them, and rode almost all the rides we wanted (only missed out on Buzz).
