Many years ago we did a cruise down the California coast and parts of Mexico; we sailed out of the port where Queen Elizabeth is docked. While boarding the ship, we sat and watched dozens of people being wheeled up the gangway, seemingly one at a time. A porter would take one up, then come back with the wheelchair and pick up another one. It turned out we had stumbled on an anniversary cruise of Mariner's maiden voyage and these people were reuniting for a cruise; we had sailed on part of her maiden itinerary so we mistakenly got the t-shirts and a couple of other things, but we weren't invited to any of the gatherings. All to say, it looked like the wheelchairs were owned by the Port Authority. There were a few incidents of near fist fights on who had the next turn.
