Welcome to planDisney, Becky!
We are so happy to hear from you, and hope that you are having a lovely holiday season! Your trip to The Most Magical Place on Earth is going to be here before you can say, "Bibbidi Bobbidi BOO!" Don't forget to pack a light jacket as the evenings and mornings can be a little chilly here in February.
I typically recommend giving about 1.5 hours (a full 90 minutes) to dine at
Cinderella's Royal Table as it is a very immersive experience, and you'll want to not feel rushed to eat or interact with the princesses. Because
Bibbidi Bobbidi Boutique is so close to Cinderella's Royal Table, a 9:20 reservation for the Boutique would probably be just fine, Becky, and you would most likely be able to see all of the princesses while you dine. I think that this plan is great, but you can always edit your Bibbidi Bobbidi Boutique reservation to a later time in advance if you feel like you're going to be rushed.
While you're on vacation, Becky, I highly recommend enjoying
EPCOT International Festival of the Arts. It will be in full swing while you're visiting, and there are so many lovely things to do for all ages! You'll also love all of the delicious foods available around World Showcase. Watch the
Disney Parks Blog for additional information as you near your trip!
If you have additional questions, we'd love to hear from you again soon! Have a great, big, beautiful tomorrow.
