Princess Cruises reports a spike in interest to Alaska with bookings to the region more than doubling following the first episode of ITV’s latest series of The Cruise.

The new series of ‘The Cruise: Voyage to Alaska’ achieved an average of 3.5 million viewers with a peak of 3.7 million and a 16% share on its screening last Thursday.

The fly-on-the wall documentary is set on the 3,100-passenger Star Princess and is the fourth to be filmed on a Princess Cruises ship.

Two further episodes will follow this week and next, on Thursday at 8.30pm.

The line’s UK and Europe vice president Tony Roberts said: “The Cruise continues to go from strength-to-strength and we’re thrilled with the response to the first Alaska episode and previous Mediterranean series.

“Alaska is a stunning setting for the documentary and has clearly captured the imagination of viewers.

“From the scenery to the wildlife to the welcoming locals it really is a very special location and we feel proud to be able to share our 50 years of Alaska experience with ITV viewers.”
