What port have you cruised to that you need or want to go back to?

I have had only one such port. I was on the NCL last March and we had a stop in Matzalan on a Western Mexico cruise. I ended up taking a van tour for only $30. Absolutely breathtaking - The beaches, the architecture, the cliffs, and the skyline on the boardwalk - All of it. I wouldn't mind staying there for a few days to explore!!!
