Beginning in Fantasyland (where the majority of the characters are appearing)
If the Seven Dwarfs are not a priority but meeting the Princesses and Princes is, we suggest beginning your evening at the Rapunzel/Flynn Rider line. Princess Fairytale Hall closes to day guests between 6:30pm-6:45pm depending on wait time. A line outside of the building to meet Rapunzel, Flynn, Snow White, and Snow Prince started forming at 6:00pm. Wait times remained steady at around 45 minutes all evening. Cinderella, Prince Charming, Aurora, and Prince Phillip had lesser waits on average 20 minutes. After the second parade, the Cinderella side was no wait.
Minnie Mouse greets guests near the castle wall across from Friar's Nook. Minnie had an average of 5-15 minute waits throughout the evening.
Mary Poppins, Bert, and Penguins met near the Carousel intermittently throughout the party. Their meeting times began at the top of the hour. Wait times were minimal.
Wendy Darling meets during the party near Peter Pan's Flight. Peter Pan will be meeting with Wendy at future parties. Wendy and Peter appear in scarves which is basically the only difference between their daytime and MVMCP appearances.
Donald Duck, Daisy Duck, and Scrooge McDuck greeted guests all night near the entrance to Storybook Circus. They met all evening with just quick 2-3 minute breaks. Lines were long at the beginning of the evening. We waited about 20-25 minutes.
Other Fantasyland characters appearing are Belle inside Enchanted Tales with Belle, Ariel inside her Grotto, and Merida at Fairytale Gardens. Each of these experiences are the same as the regular daytime offerings. To maximize your party time, we suggest meeting these characters during your daytime park visit.
In Tomorrowland, Phineas and Ferb appeared throughout the night continuously. They meet guests in their holiday hats and scarves. If time is of the essence, Phineas and Ferb also appear in their holiday outfits at Disney's Hollywood Studios during regular park hours.
Over in Adventureland, Aladdin and Abu rotate with Jasmine and Genie. Wait times varied throughout the evening. Depending on your spot in line, you may meet Aladdin and Abu or Jasmine and Genie.
Tinker Bell in her winter outfit and Periwinkle meet inside Tinker Bell's Magical Nook in Adventureland. This meet and greet is the same as during regular park hours so we suggest meeting them before the party begins. If you prefer to meet them during the party, they had no wait after the second parade.
In Frontierland, all four country bears meet at the Rivers of America. Big Al, Shaker, Liver Lips, and Wendell appear in scarves and enjoy dancing about!
Tiana and Naveen greet guests at their normal daytime location behind Ye Olde Christmas Shoppe. Wait times were minimal.
Mickey Mouse meets guests inside Town Square Theater. He does not appear in any holiday attire. This experience is the same as during the day.
There are two dance parties during MVMCP. One inside Frontierland's Diamond Horseshoe Review featuring Woody, Jesse, and Bullseye. Another inside Tomorrowland's Cosmic Rays featuring Santa Goofy, Pluto, and Chip and Dale. These experiences are not normal meet and greets. You can take photos dancing with the characters but they rarely will pose for a photo on the dance floor.
