You can get a taxi from the Epcot resorts to the front gate.
DH and I needed to be a the front gate when it opened for a tour and could not use the International gateway (not opened yet).
The doorman at the Swan flagged down a waiting taxi for us and we got to the front gate in about 5 minutes. The cost was about $5 - $10 with tip. It was much easier than allowing 1-2 hours to get there via the magic kingdom buses.
HTH.
