Hi, Shanna! My older daughter is a huge fan of Stitch, so I also have to keep up with his whereabouts at Walt Disney World Resort. A couple of years ago, she even built her birthday trip around seeing him every day at every possible location. He is definitely a treasured member of our 'ohana, so let's get you set up to make the day of your 'ohana.
Character meeting locations can often change, so be sure to pick up a Times Guide at each theme park to be up-to-date on the day's schedule. As you mentioned,
Stitch's Great Escape! is currently listed as a temporary closure. However, they do open the lobby of this attraction so guests can "hang ten" with Stitch. He is usually there from park opening until early evening, so be sure to stop by early in the day!
The most delicious way to find your daughter's friend is to have breakfast at
'Ohana. He and other Disney friends meet guests (and try to steal their Mickey waffles!) at this Polynesian Village Resort dining location every day. If you would like to visit him there, be sure to make an Advance Dining Reservation, as it is a popular breakfast!
Shanna,
Disney's Typhoon Lagoon Water Park is currently closed for its annual refurbishment, but if you plan in the future to visit it, keep an eye out for Stitch near Singapore Sal's. He and Lilo visit there often in the spring and summer.
Thanks for stopping by with your question. Please let us know if you have any other questions as you plan your magical visit!
