The privilege of being able to go direct to your "door" (to your cabin or campsite) is reserved for Disney's Minnie Van service. Mears, taxis, rideshare services, grocery deliveries, stroller deliveries, etc. are restricted to the front desk only per Disney's policy. Or your own vehicle, of course (which will incur the daily parking fee). Some folks get a FW van to move them between the cabin and the Front Desk area but I don't know the circumstances of when that is triggered.
During the covid times when the Minnie Vans were not being offered, that restriction was relaxed. Now that the Vans are back in action, so is the restriction.
Not the answer you probably wanted to hear but the one you need to know.
