It is difficult to park at the resorts, there are security gates at the parking lots. Someone said there is a public lot near the Boardwalk Inn, but I don't know where it is. The easiest way is to take time out of the day you are at EPCOT, you can walk right out, and back in again, through the International Gateway entrance in World Showcase. There are beautiful resorts to look at, shops and restaurants to check out, or just people watch.
