Hello Latoya! Unfortunately, there has been no official date from Disney yet on when Sofia the First will be making her debut at meet and greets. All we know is that she will be appearing in Animation Courtyard at Disney's Hollywood Studios some time later this summer. Hopefully that will be in time for your upcoming Walt Disney World vacation!
Doc McStuffins and Sofia the First are appearing several times daily in Disney Junior - Live on Stage!, also at Disney's Hollywood Studios. You can check your Times Guide when you arrive to see the show times.
Latoya, have you subscribed to the
Disney Parks Blog yet? I highly suggest doing so to receive the latest info, news and events at Walt Disney World, delivered straight to your in-box daily. It's a great way to keep up on all the happenings, including when Sofia the First will be appearing for meet and greets!
Thank you for your question, and please come back to the Disney Parks Moms Panel if there is anything else I can help you with - just ask! Have a magical day!
