Well, then somebody needs to tell MK Bus Ops and the FtW coordinator, because they are not aware of such a route either -- or at least were not at the time I was driving out of those hubs.
2 weeks ago I was visiting WL. I was looking for a bus back to MK, but the arrivals board said "Take watercraft". When a bus pulled into the MK load zone, the driver said that at some time in the afternoon (he wasn't sure of the time because he only drove nights and was fairly new), the WL bus starts circling from MK to WL to FtW to MK, with no stop at WL on the way back. I boarded the bus, which then went to FtW Settlement (not Outpost) and then directly back to MK.
During the years I drove out of MK, there was never a FtW bus out of load zone 2. FtW was never listed on the directory boards at the entrance to the load zones. Load zone 2
was used by the WL bus. When I drove the FtW internal shuttle, Guests were instructed to go to Settlement for the boat to MK, and to Outpost for buses to all other locations. The 2014 resort map given to Guests, scanned
here, says the same. Like I said, I retired 2 1/2 years ago, so I don't know what has changed since then, except for my personal experience 2 weeks ago.
