I know. I realize that is a temporary Port Terminal, but if Charleston can get a mobile Air Bridge - JaxPort should have done so as well by now. Who know's maybe they will. As that sure would have been easier for you if the cabins were ready when you boarded. I also would look to see if Embarkation area elevators are working. I have seen them working on some cruises from the Deck 3 Gangway. There would be a line though, and may be reserved for special needs.
