I went to the party last night! I had so much fun! I'm kind of sad that it went by so fast. I'm going to list everything and some random tips.
Getting There- I only did the party, not admission plus the party, so I left LA around 2 pm. We got to the park at 3:15ish (Thank you traffic). Parking wasn't bad at all. It was organized, but you can tell that many of the party goers were starting to roll in. By the time we went through security, tram, and got to the gate, it was about 3:55. They had everyone with a Mickey Halloween Ticket to enter the Special Events entrance. The lines were a little long, but went fast. Once you get through the turn entrance, you get your wristband right away as well as the little trick or treat bag. I highly recommend that if you want to go through all of the treat trails to bring your own bag. The one they give you is for sure not big enough.
Eating: I noticed a lot of the party guests were eating. We did the same thing. We ate at Cafe Orleans, and were seated before our reservation time. The service was very fast! It might have been the fastest restaurant I've ever eaten at lol. When we finished eating it was about 5:40.
Rides: This was the tricky part. Since we didn't come during regular admission, we missed the times for fastpasses and maxpass. After eating we decided to suck it up and do a ride before the party began at 7:00, so we waited 75 minutes for Soarin. As someone who is used to using Fastpass all the time, waiting this long was BRUTAL lol. We got off the ride around 7:15, and tried doing Radiator Springs single rider lane but that was 60 minutes and Standby was 150. We gave up and went to DLR for the party lol. By this time DCA was crazy packed! You could barely walk. I'm sure the regular guests had just left DLR to come over since the party began.
The Party: We did Space Mountain, Indiana Jones, and Star Tours and only waited like 10 minutes for each. We watched the Fireworks which were awesome! That Orb was so cool! If you want a good view, make sure you aren't near any trees. The castle looked so cool with the projections. The treat trails were pretty fun. The CM are good at giving you certain candy if you request it. Plus they have snacks if you don't want candy. We didn't watch the parade but when I got glimpses of it, I saw Ursula, Ratcliff? (the mean guy from Pocahontas), Captain Hook, and Jack & Sally. Don't quote me on this, but I think I saw Maleficent by the front entrance near the train for pictures. Again, don't quote me lol.
Tips:
1. Bring your own Trick or Treat Bag (if you want to)
2. If you are waiting around during the 3 hour window, you can try doing rides in DCA. The wait times are long, but you can get a couple in before the party begins. I would've done that but we had dinner reservations.
3. If you want to try a sit down restaurant, this is also a good time to try too.
4. Oogie Boogie buckets are sold out resort-wide (wahhh)
lol
5. THERE ARE PUMPKIN SPICE CHURROS!!!!
6. Coming in later in the day, there is only one side of trams working instead of two sides. So it made the tram wait a little long.
