Welcome to planDisney, Magdalena!
How exciting that you have an upcoming trip to The Happiest Place on Earth! I took my own little princess to the Disneyland Resort this summer and she had the most magical time. She got to meet the REAL Elsa and the REAL Mirabel at Disney California Adventure Park. Both characters were absolutely amazing and made a real effort to engage with my daughter.
I'm sorry that you're having trouble making a reservation for
Bibbidi Bobbidi Boutique. Unfortunately, this experience is extremely popular and reservations fill up very quickly. Guests can make reservations 60 days in advance of their visit. These reservations can be booked up in seconds. Therefore, since your trip is less than 20 days away, you're going to have difficulty finding availability, I'm afraid. It's possible that someone might cancel. Therefore, I would keep checking. Who knows, you might get lucky!
Let me also suggest some other ways to fill your visit with Disney Princess magic:
Purchase a spectacular gown for your child through
shopDisney. Your princess can then wear it throughout the day and get that "practically perfect" photo in front of
Sleeping Beauty Castle.
Your little princess can meet many of the Disney Princesses in the parks. In Disneyland Park, she can
Meet Disney Princesses at Royal Hall. Sometimes, there is even a Disney Princess in the area outside Royal Hall. When we visited this summer, Ariel was out there meeting Guests. (Gaston even made an unwelcome appearance and tried to steal all the attention!). You might run into Princess Tiana as she strolls through New Orleans Square and Frontierland. In Fantasyland, you could stumble into Belle and Beast.
In Disney California Adventure Park, we were able to meet Anna and Elsa outside Carthay Circle restaurant. Although she's not a Disney Princess, you can also find Mirabel close to Goofy's Sky School.
I hope that's helpful, Magdalena! I'm sure you and your group will have a wonderful time!
