NEW YORK The popularity of the Disney movie Frozen has not only led to box-office profits, sold-out merchandise and long lines to meet Frozen characters in Disney parks. It's also motivating fans to visit Norway to see the landscape that inspired the animated movie setting.

Harald Hansen, U.S. spokesman for Visit Norway, said the number of U.S. tourists to Norway increased markedly since the film's release in November, with booked hotel nights up 37 per cent for the first quarter of this year compared to the same period in 2013. He said tour operators have also seen a 40 per cent sales increase this year, compared to the same period last year, while Oslo Airport Gardermoen reported a 57 per cent increase in arrivals from New York for the first quarter.

"We noticed a huge increase from the U.S. already in November and December last year, just after we started our marketing with Disney in October," Hansen said.

Hansen said that the increase in traffic is most noticeable in the fiord region, but that there is also more interest in Oslo and Northern Norway, where visitors can see the northern lights - a phenomenon that is also shown in the movie.

Norwegian Air has also just started flying direct to Oslo from Orlando, Fla., the airport nearest to Disney World.

The Disney tour company Adventures by Disney is taking fans on a series of eight-day trips to Norway this year, priced at more than $5,000 US a person, including a visit to Geirangerfjord, the fiord that inspired the film's fantasy kingdom of Arendelle. And Disney Cruise Line plans a Norway itinerary for 2015.

Wilderness Travel, another tour company that runs trips to Norway, has also seen an uptick in interest. Even though Wilderness Travel has no formal connection to the movie, "the film seems to be a big part of the popularity," said spokeswoman Barbara Banks. "People just hadn't seen these remarkable landscapes before ... The movie represents the folk culture in such an engaging way, and the landscapes and architecture are so stunning, and they are all based on real places."

Sheridan Becker, an American mother of two who's currently living with her family in Barcelona, says she and her kids are planning a trip to Norway "all because of Frozen - our favourite Disney movie at the moment."

Pilar Clark, a mom of two who lives outside Chicago and who contributes to Babble.com's Disney section, took a Disney tour of Scotland after seeing the movie Brave and is now considering signing up for Disney's Norway trip. "When there is a connection that kids can understand, it becomes a win-win," she said. "The kids are saying, 'Let's go to Norway! Can we go to Arendelle?'"
