We went to the 10/6 party and had a great time! We went to MHP a number of years back and didn't feel it was 'worse' at DCA as others have complained but everyone has different priorities and experiences, of course. The only piece that might have been nice for them to bring over would have been the Cadaver Dans...
I should preface this by saying that I like to see characters but literally just walking by and seeing them is good for me. We don't typically do much in the way of character photos/ M&G. My older two could generally care less and my younger is both ageing out of that a bit and wouldn't recognize many of the characters (disney afternoon, kingdom hearts) and doesn't like to meet villains anyway (except Maleficent and Evil Queen). We also had no interest
Due to a variety of reasons we didn't end up getting to the DLH to check in until about 5pm then had to get ready so entered the party around 7pm (would have been earlier but the security line at DTD was NUTS!!) I guess the nice part was no lines to get in at the main gate or for wristbands. Saw Pinocchio and Blue Fairy were meeting by the fountain as we walked by which was neat. We stopped at the headless horseman statue for a family photo. Only 3 parties in front of us so that went pretty quickly. I was surprised to see how many people were already staking out spots for the parade. Seemed like a waste of party time to me since the parade was still well over an hour away, especially from that portion of the route. We headed for the Dr. Facilier immersive trail first- he was great! We then headed over the Mad Hatter trail which was also neat but the location seemed a little weird. I guess they make do with the spaces they have. Then rode GOTG: MAD (first time on that version for us- LOVED it!!). The ride was a walk on. After we rode GOTG the Headless Horseman was making his way down the parade route so we easily grabbed a spot right at the corner in front of Hyperion (but across the street). We were a couple people back from the curb but still had a great view and watched the short but enjoyable parade.
I knew there was a DescenDance party at 8:45 which was pretty much right after the parade so we crossed the street and headed back there (DD8 was dressed as Evie so she for sure wanted to go). The dancers were great but I was a little embarrassed for them that the video clips where they had the actual Descendants actors talking were out of sync with the audio- it looked terrible. My younger two enjoyed the party for a while but we didn't stay for the whole thing. We crossed back over to the Oogie Boogie immersive trail. DD8 was happy to see Oogie's platform was empty when we entered but he came out a minute or so later, much to her dismay, and then he even spoke to her too but she survived.
We then wasted a bit of time getting some dinner at Smokejumpers but the kids needed food and we hadn't had time earlier. I don't know if its seasonal or I just didn't notice it before but the pork belly and green chile mac and cheese was delicious! We did mobile order but I'm not sure we needed to as the place wasn't very busy.
Loved seeing the Rescue Rangers as we walked by on the way to the Maleficent immersive trail- she was fantastic! She and Dr. Facilier were the best of them, in our opinion. Then we headed over to the Evil Queen one. DD8 was a little bummed that she didn't acknowledge that she was dressed as Evie (Maleficent and Dr Facilier did make reference to it) as she is the Evil Queen's daughter but oh well. The villains grove line was a little crazy at that point- app said 35 min wait and it was doubled back all the way down the the Grand and back- so we decided to come back later.
Headed over to ride Ariel per DD8's request then DD14 and DD10 wanted to ride Incredicoaster so we headed over there. Then we were going to hit the CarsLand treat trails but as we walked of the Pier DD8 realized she had left her Minnie
loungefly backpack on a bench over by IC

. So she and I headed back to the area to look for it but no luck (good news though! We submitted a lost item report online and they contacted us yesterday that they had her backpack and we picked it up!) and the older two hit the CL treat trails. I forgot to warn them that the entrance to the one by Fillmore's is on the wharf and they couldn't figure it out but went to the one in the back. Our candy bags were pretty full by this point anyway.
It was just about time for the second WoC at this point and there were still plenty of good viewing options. Even though Villainous was one of the main reasons I really wanted to go the party, we ended up deciding to skip it in favor of visiting Villains Grove. I do not regret this at all. We walked into Villains Grove at about 10:45. Zero line and not very crowded so we could take our time walking through and we all thought it was spectacular. They basically had to chase us out of there at the end of the night. I will watch Villainous online at some point but the lackluster reviews de-prioritized it for me...and I figured it would translate better to watching later on
YouTube than walking through Villains Grove.
All in all we really enjoyed the party. If we hadn't gotten there late we probably would have been able to fit in WoC and a visit to the AP area but those are really the only two things we missed that we were interested in. I could definitely see things feeling more rushed if we were trying to see tons of characters though.
Over in DL yesterday the park was VERY busy during the middle part of the day. We overheard a couple of security folks saying "It's crazy today! Where were all this people in the summer??" Enjoyed the Halloween decorations as always and loved HMH, of course. Made good use of MP and several times scored almost immediate FPs by frequently refreshing (including for HMH and HSM). We tried the wedding cake and doom buggy cake at French Market- wedding cake was soooo good. Doom Buggy was...eh. Maleficent churro was also meh (and made your lips and mouth a really gross green color). Really liked the loaded fleet fries at Galactic Grill and didn't think they were too spicy.
