Ships are actually very energy efficient, those people probably would use more gasoline during their daily commute since each of them would drive a car or take a cab. If they went on a plane somewhere for vacation, it would use a lot more fuel

They are all taking a plane down to Ushuaia, and from there getting on the cruise ship. So they're doing both.

The big ones are efficient per person, yes, but these ships are smaller.

The worst part of the waste, particulates from combustion, end up on the glacier, darkening it, making it melt even faster.

Don’t cruise ships use bunker fuel?
