This is possibly the most annoying Disney urban legend of all time. The idea that they named the park because of its supposed central physical location within Walt Disney World is exceedingly silly. As Martin noted, the EPCOT symbol in the ground wasn't even there until 1994. Beyond that, the center of WDW property constantly shifts all the time as Disney gains and loses land. For another thing, if that was the basis, then they certainly wouldn't have taken that word off the name. The idea behind the Center added to EPCOT was to give the idea that this was the heart and soul of WDW, and give people the impression of a hub for emerging ideas and technology. And to help distinguish it from EPCOT the city, which it decidely was not.
