Hi there Mercedes,
So glad to hEAR from you again! Mickey and his crew love spending magical birthdays with Guests.
The Disneyland Resort is all about celebrating-whether it is for anniversaries, graduations, first visits, birthdays, engagements, marriage! You will not need to provide any proof that it is your daughter’s birthday during your visit to The Happiest Place on Earth. One of the easiest ways to let everyone know it is your princesses birthday will be to stop by City Hall and get her a free 'It's my Birthday' button to wear during your visit. Then all Guests and Cast Members that see her in the parks will be sure to send her birthday wishes throughout the day. (I know I try my best to wish every Guest I see in the parks wearing that button a Happy Birthday!)
Also if you decide to go with one of the makeovers I suggested before, like at Bibbidi Bobbidi Boutique located in Fantasyland, you can get her a royal birthday sash to wear. My daughter felt like royalty in her pink sash and oh-so-very special! You can book a regal transformation for your birthday girl up to 60 days prior to arrival by calling (714) 781-STYLE or (714) 781-7895). Reservations are highly recommended.
If you have any more questions, please
write me back, I'm here to help you plan your next pixie-dusted vacation.
Wishing you magic!
