We spend a staggering £670 billion pounds a year on hotel holidays. With over 700,000 hotels and resorts around the world to choose from, there’s something for everyone. Whether you’re after swanky 5 star opulence or a homely B&B, when these hotel holidays go right, they’re perfect paradises and much needed R&R. But when they go horribly wrong, they can be cataclysmic.
