Please note that you don’t park next to the MK. You park at the TTC and take a ferry or monorail (or walk, but it’s a major hike) to the MK.
You can walk, take a Friendship Boat, or the skyway between DHS and the International Gateway to Epcot, (walking is always an option- it’s less than a mile). The boats and the skyway operate for quite a while after the parks close.
if you left your car at DHS and we’re at the MK or AK, you could take a Disney bus to the.Beach Club, Yscht Club, or Boardwalk and walk back over to DHS.
There is NO FOOTPATH. between the main entrance of Epcot at thee international gateway.
