I am an Orlando native and have been to every theme park many times, and EPCOT is still at the top of my list. You need two full days to really enjoy everything this park has to offer.
EPCOT is a wonderful blend of culture, science, delectable cuisine, and fun. You will think you've stepped into other countries as you go from Mexico to Morroco in World Showcase. And each country has restaurants featuring its nation's cuisine. These restaurants only employ people from that country, to ensure authenticity, and the food in these restaurants is second to none. Sample some bratwurst in Germany, sushi in Japan, and have a Napoleon in the French pastry shop. In Future World, there are fun and educational things to do, as you learn about nature, the body, the ocean, dinosaurs, on interactive rides and shows.
