Hello there, Mary! Welcome to planDisney! We are thrilled to hear you are going to be visiting Disneyland Resort so very soon!
Wow! I am so excited for your prince or princess and that they will get the royal treatment at
Bibbidi Bobbidi Boutique! If you have a reservation for California Adventure that day, you will not be able to park hop until 11:00 a.m., which does not work if your Bibbidi Bobbidi Boutique reservation is for 10:40 a.m. that day. Since you have park hoppers, I would think about swapping your
park reservations for the day to Disneyland. I know that may mess up the plans if you are doing multiple days, but that is probably your best option. You can always continue to check availability for Bibbidi Bobbidi Boutique to see if you can modify your reservation or get a later time, but these reservations are pretty popular so I am not sure how likely that is. If you have a Disneyland day prior to this day, you could also attempt to head there when the boutique opens to see if they have any same-day availability.
You will for sure want plenty of time to enjoy California Adventure with the
Food & Wine Festival going on. I've been there twice so far to try some festival foods, and my favorites so far were the Burrata Toast at Aunt Cass Cafe and the Mickey-shaped Macaron made with SNICKERS at one of the marketplace kiosks.
Mary, I hope you figure out the best plan for your party. If you have any other planning questions, you know where to find us!
