The HDDR is at Fort Wilderness, not Wilderness Lodge, they are 2 different places. So to get from MK to FW the boats are generally
ECV friendly. From WL to MK two different size boats usually work the route, the larger one is the same as the ones on the FW/MK route, so everyother boat from WL/MK is ECV friendly. There are no buses from FW to MK so the boat is your only direct option.
