Our car service dropped us off at the Outpost and our Walmart grocery order arrived as we were checking in. We had a Fort Wilderness van take us (6 people), our bags and our groceries to our cabin. When checking out a van picked us up at the cabin and drove us to the Outpost where we met our car service. Only cost was a generous tip to the CM-driver.No. Ride shares, taxis, etc. cannot go directly to cabins or campsites. They are to be met at the Outpost (check-in building area).
Direct-to-your-front-door is a privilege reserved for Disney's own Minnie Van service (to make it worth the extra cost I guess).
