I don't think anyone does a better job of "Making you feel special"
than Disney and I would be inclined to suggest a PS at a Resort. Tell them that its a special occassion and remind them again when you get there.
Go to the Gala dinner perhaps at The Grand Floridian. There are characters including Prince Charming and if you talk to the servers and characters they will make a fuss of your daughter. The surroundings are so nice you will feel okay to dress up even if others are in park gear.
Its a buffet meal at 1900 Park Fayre within the hotel.
It costs $23.99 each adult. There will be live music in the atrium nearby. If the pianist is at the grand piano I am sure he would play a request for your daughter.
Sorry if your nor Disney fans, this suggestion will be way off the mark.
