Hey there, Kelly! Thanks for stopping by the Disney Parks Moms Panel with your question.
You have got to be getting so excited for your upcoming
Walt Disney World vacation. It is right around the corner! If you have your tickets linked to your
My Disney Experience account, you can actually make your
FastPass+ selections now. Guests staying at a Walt Disney World Resort hotel can make their selections up to 60 days in advance and Guests staying at other hotels can start making their selections 30 days in advance. Any Guest that enters the FastPass+ queue for an attraction will be required to have a FastPass+ selection for that specific attraction. So, yes, all of the adults in your party would need a FastPass+ selection to see her meet all of the characters.
If you don't want to use a FastPass+ selection for meeting characters, another great way to still be able to spend some time with them is to book character dining experiences. We did this a lot when my daughter was younger and obsessed with character meet and greets. It saves a lot of time waiting throughout the day because you aren't waiting in lines at the park, the characters come to your table while you are eating. Knocking out two birds with one stone kind of thing.
Cape May Cafe at Disney's Beach Club Resort has a fabulous character breakfast that the whole family will enjoy. The food is wonderful and Minnie and her pals are dressed up in their beach attire ready for a fun day in the sun! It's a unique photo opportunity with them. Another great character meal is the Bon Voyage Adventure Breakfast at the
Trattoria al Forno Restaurant found on the BoardWalk. Here you can dine with dynamic duos like Ariel and Prince Eric and Rapunzel and Flynn Rider as they set out around the room to welcome all of their Guests. It's a really fun breakfast with some really great food. I think that your entire group would love a character meal and being able to use that FastPass+ selection for a different experience.
I hope this helps! If you have any other questions, please feel free to come back and ask.
