Plummeting demand means there are some good hotel deals around at the moment, especially at the higher end of the market. If you don't like the idea of haggling directly, this site is a useful comparison tool. Hotels contact Laterooms if they have late availability and are willing to hack their prices in favour of higher occupancy and beady-eyed browsers can bag a deal. It has a global reach, though it does most of its business with UK and European hotels and there's no booking fee.
