The EASIEST would be to take a cab to FW. Then take a bus to the Settlement Depot which is where the HDDR is located.
Option 2: From AKL, take any bus that arrives first to AKL. From MGM, Epcot, AK, take the bus going to FW. Finally, take the Internal Bus at FW to the Settlement depot.
Option 3: Same as above, but if bus is at MK, you can take the boat over to FW. This will drop you off at the marina which is right next to the Settlement Depot.
Returning back to AKL, you can either call a cab from FW, or take a bus to Downtown Disney. Then transfer to a bus heading for AKL.
