Overall: Great party. Really well themed.
Saw the characters exactly as
@Vala reported above, also saw Loki walking around by Monsters Inc. Also Mickey and Minnie are in adorable new outfits over near Grizzly, but that line was CRAZY every time we saw it. (Character hosts were saying there were issues with costumes and such that delayed many of the first sets, seemed a little chaotic until 7).
For the “immersive” treat trails:
Oogie Boogie - Animation Building
Maleficent- by Soarin’
Wicked Queen - by Grizzly
Dr. Facilier (sp?) - whatever that building is between Monsters Inc and Philharmagic
Mad Hatter - Hyperion
**Oogie Boogie was the highlight, but they were all great. They didn’t all open on time - Hatter wasn’t open yet at 6:40, but Oogie Boogie was.
**The lines can look long but move fast (assuming it’s open, don’t waste time waiting for an unopened one).
The Villians’ Grove is gorgeous; I’d love to see them add some characters/performers here. The line was CRAZY right after the parade, but we came back at like 10:10 and it was much shorter. We spent 20 minute in the actual Grove after waiting in line, so plan accordingly. It also doesn’t open until after dusk since it needs to be dark for the projections to be visible.
The parade was nice; we got spots for six in front of the Grizzly waterfall (right by the Kingdom Hearts M&G) at 7:45.
I walked up to the second WOC right as it started at 10:45 and there was plenty of viewing.

Honestly I thought it was kind of boring and bailed before it ended.

And I’m a WOC fan - Seasons of Light is like my favorite thing. So this was a bummer.
We didn’t ride anything, so no reports on that. Rides we saw had minimal waits.
The Decendance party and Disney Jr building show seemed cute for kids, but not super popular (well, the early Disney Jr shows were, but not the later ones).
I’ll probably come back with some more pictures and/or details tomorrow.
