Expedia has been drafted in to power hotel booking site CheapHotels.co.uk.
The partnership gives users the ability to choose from more than 195,000 hotels worldwide.
Activities and tours have been added to the site as a result of the tie-in with Expedia.
CheapHotels.co.uk is part of the Federated Travel group of hotel sites, which includes ParisHotels.com, NewYorkHotels.com and BoutiqueHotels.com.
Chief executive Juan Palacio said: “We have improved the way we are grouping the product, making it really easy for travellers to find the best deals with social components.”
