Actually that site says it takes 13 minutes by bus from EPCOT to MGM. don't know if someone thinks you have to take all the possible steps they show as it also lists the time for the same places by boat. There was a time a few years ago that you could not go from park to park by bus without going to a resort or the T&t center. I think the OKW bus from DTD stops at TL on the way to OKW
also.
