The Red Carnation Hotel Collection has become the first hotel group in the UK to add its properties to the TripAdvisor instant booking platform.
Currently only available to use in the US, the initiative allows travellers to make a hotel booking through TripAdvisor's online travel agency partners without leaving the TripAdvisor website.
TripAdvisor launched the instant booking platform in June 2014.
Jonathan Raggett, managing director of Red Carnation Hotels, said: "We're excited to be the first UK hotel collection to join the new TripAdvisor instant booking platform. Guest service is at the absolute heart of everything we do, and this integration importantly makes the booking process simple and seamless for guests using TripAdvisor."
"Our relationship with TripAdvisor is a valued one. Our hotels are consistently rated highly on TripAdvisor rankings and our three London five-star properties have featured as the top three hotels in London for the past five years. It's a transparent benchmark showing that we continue to meet and exceed our guests' expectations time and time again."
The Milestone, one of Red Carnation's hotels in London was recently placed second, behind the Haymarket hotel, in the TripAdvisor Travellers' Choice Awards 2015, having topped the list last year.
The Red Carnation Hotel Collection owns seven hotels in the UK, as well as a further seven in Ireland, Guernsey, Geneva, Florida and South Africa.
