We’ve been on several cruises where we never left the ship. Most of ours have been in the Caribbean. Once you’ve been to Cozumel, there’s not a big reason to go back. Besides, once everyone has left the ship to go on their excursions, there’s lots of room on the ship. But, no, one does not have to disembark.
Cozumel and Dominica also...those ports are sea days for me...
