Hi Ana ~
I'm not sure when you're planning to visit the Walt Disney World Resort, but Moana is appearing at
Mickey's Not-So-Scary Halloween Party. It is held on select nights through November 1, 2017 and requires a special event ticket to attend.
While it isn't a meet and greet opportunity, there is a segment that includes Moana in
Happily Ever After at the Magic Kingdom. Make sure you're on the front side of Cinderella Castle to be able to see the projections shown on the castle.
Having said all of this, Disney is always keeping us on our toes so I'd suggest keeping your eyes on the Disney Parks Blog for any announcements regarding if and when Moana will return during regular theme park hours.
Currently, Stitch doesn't have a permanent meet and greet location. However, we often see him in the Magic Kingdom in Tomorrowland near the Tomorrowland Transit Authority PeopleMover. We have also seen him near the Flag Pole in Town Square. If you're visiting Disney's Hollywood Studios, we have sometimes seen Stitch in the area in front of the Grauman's Chinese Theatre.
I'd suggest downloading the My Disney Experience mobile app prior to your trip. You can check for character appearances on the day you visit the parks to see if Stitch is appearing. Also pick up a printed Times Guide as you enter the parks. If you don't see Stitch on either, check with one of the Cast Members in the blue shirts that are with any of the characters.
You can also find Stitch at the
Best Friends Breakfast featuring Lilo & Stitch at Disney's Polynesian Village Resort. Advanced dining reservations are highly recommended at this location.
Wishing you minnie magical memories :-) Allison V.
