Hi, Hazel! This sounds like the makings of a supercalifragilisticexpialidocious birthday! I am pleased to tell you that you will be able to bring your balloons into Magic Kingdom Park to take this practically perfect picture in front of Cinderella Castle. At this time, the only theme park guests are unable to bring balloons into is Disney's Animal Kingdom Theme Park. So you should be fine the morning of your big day to mark your grand birthday with a royal balloon-filled picture.
You may want to look into Memory Maker One-Day for this day, if you are not already including the full
Memory Maker product into your visit. With the One-Day option, you are able to download all photos taken on one specific day. I am guessing you are going to have quite a few since it is your birthday! To purchase
Memory Maker One-Day, just pull up one of your Disney PhotoPass pictures right within your
My Disney Experience mobile app. You will be given the option to either purchase this picture, purchase Memory Maker, or purchase all pictures taken this day. If you choose the latter option, then you will have access to unlimited downloads of Disney PhotoPass pictures taken throughout that day. If you have any issues with activating this, just stop by any of the
Disney PhotoPass Centers. There is one located within Town Square Theater near the entrance to Magic Kingdom Park.
I hope you have the happiest of happy birthdays, Hazel! Please let us know if you have any other questions as you continue to plan your pixie-dusted birthday celebration!
