Cruise ship holidays are growing in popularity each year thanks to their affordability and ease of travel. But whether it’s a weekender cruise just off the coast or a month-long journey travelling around the world, the all-inclusive nature of cruise holidays means there’s a lot going on behind the scenes to keep these massive floating cities functioning. No matter where you plan to visit on your cruising holiday, often the ship itself is just as important as the destination. With so many on board facilities and holiday-makers to serve, it takes a lot to keep these marvels of modern day engineering afloat, not least of which is keeping thousands of tourists in a steady supply of food and drink. Every year the cruise industry releases some mind-blowing numbers, but these take the cake.
