Hi Elise,
We love Lilo and Stitch so much we have cats named after them! Lilo (the character) always gets excited when we tell her about Lilo (the cat.) The best way to meet Lilo and Stitch at Walt Disney World is the
Best Friends Breakfast at 'Ohana in Disney's Polynesian Village Resort. We just enjoyed this breakfast last month. The food was delicious and the character interaction was fun!
You can also meet Stitch most afternoons at the Magic Kingdom. He likes to hang out near the attraction
Stitch's Great Escape in Tomorrowland. I have to admit, even though I love Stitch I am not a big fan of this attraction.
As this is your first visit, my best advice is not to try to do everything. It's very close to impossible to see everything in one visit. Pick out a few priorities and then whatever else you are able to see and do is a bonus!
Thanks for stopping by the Disney Parks Moms Panel. Please let me know if I can help you with any other questions!
Wishing you a magical vacation,
Amy H
