You can visit five or six locations or 20 or more for the options and destinations are now diverse.
You get a room and it gets attended to.
You get meals and you get to enjoy a passing maritime vista while enjoying a cool drink while encased by a deckchair.
You get taken city to city so no need to find parking and no need to queue up at some airport for what often seems like a fortnight.
It has revolutionised the tourism industry and the benefits are clear.
Holidaymakers buy things and if that holidaymaker is sad at having to leave a pretty and friendly place then they will likely return.
As I was told - a cruise ship visit is effectively a "taster" for many people who return home and plan a longer visit next time.
It's a slice of the tourism market we here have fortunately become a leading part of...it needs to be valued and embraced.
