Hi Nicole!
Thanks for your question and Happy New Year!
What a splendid way to spend a birthday...by visiting
Walt Disney World Resort!! You'll be happy to know that Happy Birthday buttons are available either AT your resort AND at
Guest Services in each of the theme parks! Your choice!!
I always prefer getting mine at resort check-in so the kids can put them on before beginning our day's adventure in the parks. Cast Members do an amazing job seeing/recognizing the button and wishing each little prince or princess a cheery "Happy Birthday!"
As for any special "magical" moments at dining locations, there is nothing etched in stone that will definitely take place, but it is ALWAYS worth mentioning the occasion to your server. You just may be surprised!
I hope this helps and I wish you a Magical trip!!
Chris
