I would walk, boat, or ride Skyliner to DHS to avoid traffic on BVD, then take bus to the Fort and internal bus to the Settlement.
The usually recommended route of bus to MK may run into backed up traffic approaching MK, for 2 reasons: road closures for perimeter fireworks, and just generally heavy traffic.
Bus to MK, then take the boat to FW. The boat dock is only a few minutes walk from HDDR, no need to take internal FW bus. If you want to completely avoid the roads and have park hopper tickets, walk through EPCOT and monorail to MK or Contemporary and take a boat to FW.
