Hi there, Miss Deborah!
Thanks for bringing your great question to the Disney Parks Moms Panel. I'd be delighted to help you with planning your next trip to the Disneyland Resort.
While you can always change your mailing address on your online
Disneyland.com profile, you will need to call Guest Services directly if you have any changes to make to your birthday at (714) 520-6222. I'm sorry that you cannot make these changes yourself online.
Before you arrive to the Disneyland Resort, make sure you download the
Disneyland mobile app. This handy app will be your number one tool to navigate the parks when you arrive. I love viewing attraction wait times and Character locations on the app as well as mobile ordering food and beverages at select Quick Service restaurants in the parks. This app truly has maximized our time in the parks allowing us to experience more entertainment and ride more attractions.
Please return if you have any other questions, and have a Zip-a-Dee-Doo-Dah day!
