Hi Sydney,
Thanks for visiting the Disney Parks Moms Panel with your question! When my daughter was younger, we spent most of our days at Walt Disney World Resort meeting characters, it is truly magical seeing the look in younger children's eyes when they meet their heroes.
When booking
FastPass+ Selections, everyone in your party who will be enjoying the experience will need to have a FastPass+ Selection. Since your daughter is only three, you will need to book a FastPass+ for yourself as well. If your daughter loves meeting characters I would recommend securing an
Advanced Dining Reservation for a character meal or two. We love
Chef Mickey's to meet the classic Disney Characters, and
Akershus Royal Banquet Hall to enjoy dining with the princesses. For my daughter the Character Meals were a good place to meet several characters at once, while not having to wait in line in the Theme Parks. Given the number of characters you will meet at the Character Meals, it would really cut down who we needed to find in the Theme Parks.
I hope you have a wonderful time at Walt Disney World Resort, Sydney. Please let us know if you have any other questions, we are always here to help.
Stephanie
