we are going to both Disneyland and Disney’s California adventure Monday and Tuesday and I am just wondering are there any characters not listed on the app that we may run into or meet and greets that we should know about so that we don’t miss them?
TONS. "Atmosphere" characters are rarely listed on the app. You'll find the most in Fantasyland and Avengers Campus. Others pop up randomly anywhere from Main Street to the Hollywood Backlot (where they've had the sensational six out a lot lately in classic outfits). Also check the meet and greet area next to Zocalo in Frontierland as well as the bridge past Big Thunder heading toward Fantasyland and the area around the Golden Horseshoe.
