Epcot has become my family's favorite park at Disney World because of rides like Soarin', Test Track and Spaceship Earth. But we still had trouble getting our then 6 year old son to have a good time in World Showcase.
Before our last trip, I heard an episode of the WDW Today Podcast where they were talking about the Epcot Passport, so I decided to give it a try. Kian was able to take it to a special table in each of the countries of World Showcase and a native of the country would put a stamp in the book and often write hello in their language.
Kian got a HUGE kick out of this and it became a game for him learning where a new country began and then looking for the right person. Some of them were located deep in the back of the country area so it was a fun challenge for him to locate them at times.
It was really nice to find something that not only kept him entertained but was helpful in teaching him about other places and cultures. This coupled with the Kim Possible Missions has really made World Showcase kid friendly.
