We always use Disney transportation after we park the MH. Busses to HS and AK, and boats to MK and to EPCOT (with change to ferry at MK, then monorail from TTC to EPCOT). This last route is mainly because our kids love to ride the ferry and monorail. We use internal busses if we are far from our destination (like Loop 400 to the Outpost), but just walk if we are reasonably close (like Loop 400 to the Marina). The only exception to ALWAYS is is we need to make a grocery or medication run. Then we rent a car or beg a ride from a friend.
