Douro river cruise bookings have doubled since the first episode aired, making the region Riviera Travels highest-booked.
Featuring on two episodes 'Cruising with Susan Calman' on January 26th and February 2nd, Riviera Travel reached over 1.1 million viewers during the broadcasts, where Susan sailed aboard Douro Elegance.
The show put the ship's onboard restaurant, sun deck, lounge and bar on full display, alongside destinations along the river from Porto to Salamanca.
Riviera Travel's chief executive, Phil Hullah, said he was "thrilled so many viewers tuned in..." adding the interest sparked from the show "was reflected in the strong website traffic spikes during the show, with highly engaged users searching and browsing our river cruise holidays."
