Smarter Travel Media, a subsidiary of TripAdvisor, has launched a new hotel booking website that automatically rebooks rooms if they become available at a lower rate.

Tingo is designed to enable travellers to book a "Money Back" room from an extensive list of properties powered by the Expedia Affiliate Network.

After a booking has been made, the website will monitor prices and automatically rebook the room if the rate drops. The difference in price will then be refunded to the traveller's payment card.

Around 95 per cent of hotels on Tingo could earn travellers a "Money Back" refund, while the rates will remain competitive even if the price isn't reduced after completing the booking.

Smarter Travel Media general manager David Krauter said: "Travellers could have saved millions last year had there been a simple system in place that automatically rebooked their room.

"And that's what Tingo does, by taking the gamble out of booking and refunding travellers' money when rates drop. It's a no-brainer."

The launch of Tingo comes months after BackBid was unveiled, a travel website that allows people to post details of an existing reservation to other hotels at the same destination.

Hotels compete for your business by offering email discounts and value-added services. BackBid users can then make the new booking and cancel the existing one if preferable.
