I’ve been on four cruises. They are great for visiting many hard-to-reach spots, like the Aleutian islands and Alaska, or low-population islands in the pacific.

They are terrible for visiting crowded, small cities, like European “old towns” like Venice and Amsterdam, where there’s already plenty of $15 flights from other major population hubs.

Easy to fit one ship load of people onto the large beaches of a small Vanuatu island. Hard to shove three ship loads of people through the Anne Frank museum.
