I’ve gotten a good idea of tourists’ preferences (and the way they’ve changed) over the last two decades. People these days are in a hurry. Boat trips used to last an entire day; now they want them done and dusted in just a few hours, sometimes no more than one, before they move on to the next thing on their to-do list. That said, sights – whether the stunning natural environment or beautiful city views – are still important to them, of course. But everyone’s got a schedule these days, and they’re invariably full.
