You can stay in a 4-star London hotel from only £42 per room, per night when you book through hotel discount specialist WTP (World Travel Plus). And we found plenty more 4-star hotels on sale at 2-star hotel prices, as you can see from the list below. Hotels use WTP (World Travel Plus) to sell off otherwise empty rooms at a huge discount – but they don’t want to publicise such low rates. That means you won’t know the name of the hotel before you book, but you’re sure to be making a saving! For Details: http://www.worldtravelplus.co.uk/services.html
