Talk to the Cast Members! They're called "Cast Members" because they are part of the show. Ask them where they are from and how long they have been at Disney. Chances are, you will hear some great stories or get some good tips. Many of them live in Florida now but have their city or country of origin listed under their names on their name tag.
The Cast Members in the Epcot World Showcase pavilions are often from the represented country, giving you a unique opportunity to ask questions and visit with someone from another culture...someone who has intentionally chosen to interact with tourist! This is also true of the Cast Members in the Asia and Africa part of Disney's Animal Kingdom park and the Goodwill Ambassadors over at Disney's Animal Kingdom Lodge.
Here's another great tip - take time to talk to me, Toni, before your trip. I can help you plan a great Disney World vacation starting with narrowing down hotels to those that are right for your budget and then we'll tackle dining and FastPass+ reservation and itineraries that keep you ahead of the crowds.
