The spec sheet says 102 bathrooms (51 men, 51 women.) I don't know what kind of generators they have but it is not going to be pretty after 24 hours.
They'd be better off with porta potties if the power and water goes out.
Might as well have no bathrooms after the sewerage gets flooded.
I truly believe that the active military & Natl. Guard will have to be called in to help.
Anyone stationed in Europe during the cold war was at least minimally aware of massive evacuation plans for planes into Europe with troops/supplies---refuel--planes out with dependents. BTW---the most expendable soldier was assigned to "escort" dependents to the departure airport.
