If I want to leave Epcot to walk on the boardwalk from the world showcase entrance can I get back in at that entrance to WS instead of having to walk all the way to the front of Epcot. I wanted to show my sister the boardwalk and then pick right up where we left off in the countries without adding extra walking. I didn't know if they had a cast member standing there to check tickets or a ticket reader to get back in.
