Hotels make big profits on Fridays and Saturdays, when their rates shoot up by around 30 per cent (or even more).

Book on a Sunday, usually the quietest night of the week, or go for a midweek break, and you can save a bundle. And check out any seasonal deals, which may be hidden away in hard-to-find ‘offers’ sections on websites.

If you’re lucky, you could pick up cash credits for meals, spa treatments and even ‘unlimited’ prosecco. Here, we’ve done the digging to root out some of the most enticing time-sensitive deals . . .
