On the seven cruises I have had the Captain switch ports only once, because he wasn't able to safely tender in Catalina. So Catalina became a sea day and we did Enseneda and Catalina back to back. I heard someone complain that the ocean wasn't "that bad'. But as I looked around the ship at some of the older people on board I knew the captain made the right decision. I would prefer to skip or delay a port then cause injury or death to anyone on board.
