Hi there, Alayna!
Either location of the
Bibbidi Bobbidi Boutique you choose will work fine for a three-year-old; it all depends, really, on what you want to do afterward.
If you plan to spend a day wandering the
Magic Kingdom with your little one in full Princess regalia, then definitely head toward Cinderella Castle for the makeover. If your goal is to shop and "hang out," then Downtown Disney might be right for your traveling party.
That's the practical answer. The magical answer? If you can, take one of your Park days and take her to Cinderella Caste for her transformation. Having the experience actually located in the Castle lends it such an incredible dimension of specialness.
And then she can spend the rest of the day in the Magic Kingdom, feeling really part of the entire atmosphere. Think of the pictures you'll get when you bring your little Princess to
meet the Princesses in City Hall in Town Square! The memories will be priceless.
So on "convenience", the two locations are a coin flip. But as for pure magic? Nothing will top Cinderella Castle and a day at the Magic Kingdom.
Give a call to (407) WDW-STYLE, and let the transformation begin!
See you later, celebrator,
