The usual advice is to take the boat from MK to Ft. Wilderness. Other options are to drive or take rideshare, in which case you’ll be dropped off at the Outpost entrance area and take the internal bus to the Settlement where HDD is. Or you can take a Minnie Van, which drops you off at the Settlement bus stop. Finally, there’s also a bus from Wilderness Lodge to FW that drops off at the Settlement bus stop.
