All Star Movies was Minnie switching with Mickey, dark suit with top hat.
Fort Wilderness had Woody, no idea who he was switching with. Probably Jessie.
OKW had Mickey on Halloween night, but I can't remember which outfit for the life of me. I want to say some sort of vampire, I seem to recall a cape with cobwebs. The night before it was Pumpkin Donald.
Music had Panchito and Donald switching, correct.
POFQ had Tiana and Louis alternating.
Port Orleans Riverside had Goofy and Mickey in orange-black outfits, my a9 Mickey photo is from there.
Contemporary had Chip and Dale in the outfits they usually wear at the Festival of Arts, I think they were switching with Minnie.
The Chip and Dale Saratoga outfits are in my picture a3. Only the two there, no switches.
Typhoon Lagoon had tried a dance party with Cop and Robber Chip and Dale (picture a2), but I was told this was changed to a regular meet later.
That's all I can add for now. I have seen pictures of AoA and the Animal Kingdom resorts online, I will see if I can find them again.
EDIT: Found pictures I remembered. 360degreesofDis on Twitter has a lot of outfit pictures if you are ever looking for something like this.
Art of Animation: Pluto in life vest.
Pop Century: Mickey switching with Minnie, clothes look very bright and flowery.
Mickey's BBQ: Scarecrow Mickey, Minnie in a yellowish checkered dress with an apron, Sailor Chip and Dale, Pluto with some googles, probably meant to be an aviator. Goofy looking a lot like the Pete's Silly Sideshow outfit, Pumpkin Donald.
AKL: Safari Daisy, looks like outfit from Tusker House, switching with Pluto, can't really make out outfit.
Carribean beach: Pirate Goofy switching with Pirate Pluto - Goofy's pirate outfit is slightly different from the
MNSSHP one.
Beach Club: Minnie in a red outfit, not sure if meant to be a Gypsy or a female Pirate.
