Here's your shortcut. Unless you are going to DTD do not use the WDW Eastgate entrance to get to the parks. Eastgate entrance takes you down Hotel Plaza Boulevard and past DTD, with many stoplights (8 to Epcot Center Drive and 13 to World Drive) and much traffic. Instead, take Vineland Apopka south past the Eastgte and get on I-4 West Tampa. On I-4 do not merge in with traffic but stay in the far right lane of the entrance ramp. This far right lane is an exit only lane, which you will take (exit 67, formerly exit 26a), that puts you right onto Epcot Center Drive, thus bypassing all the stoplights and traffic. From here, just follow the signs to wherever you want to go.
