Hello Matthew! Glad to have you visit the Disney Parks Moms Panel! I've got to tell you that I love the spirit of your question!
While you will be able to experience the the beauty of the 11 countries in the World Showcase by visiting
EPCOT, I am afraid that you will not be able to enjoy the alcohol served in each of those countries. While you definitely feel like you are in the countries of the world while visiting EPCOT, you have to remember that you are still firmly planted in central Florida, U.S.A. where the drinking age of 21 must continue to be observed. Sorry, Matthew!
Matthew, I will tell you that one of my favorite visits to the Walt Disney World Resort was the summer after I turned 21. It was a great experience back then and I think the options are even better now! There are some great bars and restaurants to enjoy in
Disney Springs. I recommend Jock Lindsey's Hangar Bar and City Works! Of course, for when you're 21.
Hakuna Matata! Jonathan G.
