What are some good ways to propose to a girl at Disneyland on her bday?

There are many magical places in Disneyland. Pick her favorite place ( with a few questions you can find this out) and have one of the Disney characters deliver flowers to her ( call them to arrange it). Frankly, I would do this at night because Disneyland is magical at night with the little lights in the trees. In front of the castle would also be a good place to propose.
