While this might sound like an obvious one... but cruise ships move! Which means you get to visit two, three and sometimes MORE destinations, on one cruise. Take a cruise of the South Pacific for example, on some itineraries, you’ll visit multiple islands across New Caledonia, Vanuatu and Fiji!
So, how does it compare to flights?
If you were to plan a holiday flying from Australia, you would need to factor in the price of flying between these island destinations, as well as flights to and from home base, which can quickly increase the price.
