Two weeks ago we tendered at both Cozumel and Grand Cayman. Many people complain about tendering, but we love it. At Cozumel they were state (Mexico) ferries holding 300 people. (By the way, the best t-shirts are $5 on this ferry). They are very careful with the passengers; we had a wheelchair on that ferry. In Grand Cayman it is the ship's individual tenders that bring you to the dock. These are fun to ride and the trip in is short at both places.They all go back and forth as long as the ship is in port. They stop 30 minutes before departure.
