Hey there, Mariana!
Thanks for bringing your question to the Disney Parks Moms Panel. Just like your daughter, my son cannot wait to say "Bonjour!" to the over-the-top
Fancy Nancy herself later this spring at the Disneyland Resort!
Make sure when you arrive, you have the official
Disneyland app downloaded to your mobile device. Here you will be able to see the locations and times of Character greetings in both Disneyland Park and Disney California Adventure Park. While Character appearances are always subject to change, we don't know as of yet if Princess Sofia will be meeting Guests during your trip, so your best bet is to keep your eyes on the Disneyland app as Characters at the parks can change every day.
Since it sounds like your daughter is a fan of Disney Junior shows, she will LOVE the
Disney Junior Dance Party! in Hollywood Land of Disney California Adventure Park. This show just added the ghoulishly delightful Vamparina to the lineup of Disney Junior pals, so I'm super excited! This entertainment option is a wonderful place for little ones to dance off some energy and for parents to get a little rest and relaxation.
I hope this helps, and remember You've Got a Friend in Me here at the Disney Parks Moms Panel if you have any other vacation-planning questions!
