doubt you went from Fl to Nantucket, non stop without any contact with others or their property. Fuel for travel, replacement of perishables all become issues... Did you not stop in any of them for food or fuel?
Fuel and to walk the dogs, period. Both very much easily distanced from everyone else. The CG we stayed in (until they were all closed and we slept in rest areas) were contact-less check-in and everyone kept to themselves. When we got to the ferry we had contact-less check-in and were asked not to leave our vehicle.
