I noticed that more cruisers than ever are staying on board their cruise ship rather than getting off in ports to self-explore or go on excursions. With many changes in ports and on ships in recent years, I too have started remaining on board in more ports too. There were even two cruises in the last year where I did not get off the ship in any port at all! What is going on? And why and when should you also make the smart choice to stay on board in port?
