BERLIN (Reuters) - Europe's tourist hot spots are looking for new ways to cope with "overtourism," where cities like Venice, Dubrovnik and Barcelona are struggling to manage huge crowds arriving daily on cheap flights and cruise ships.
They are turning to smartphone apps and car-sharing promotions to try to cope with the overcrowding, which has upset the local population and also the tourists.
Some 9 percent of travelers who took part in a survey by consultancy IP said that overcrowding affected the quality of their trip last year.
Security concerns over beach destinations in Egypt and Turkey and a rise in cheap flights have boosted growth in international arrivals to countries like Spain and Croatia to more than 10 percent over the past few years, according to data from the United Nations World Tourism Organization (UNTO).
"Overcrowded destinations are successful, but there is a thin line between success and failure," Dubrovnik mayor Mato Frankovic told Reuters at the IT travel trade fair in Berlin.
But rather than trying to limit the number of visitors, who spend money on hotels, meals and souvenirs, the cities are coming up with ways to channel tourist flows away from the most popular attractions.
Dubrovnik aims to launch a smartphone app by the end of 2018 that lets users know when the narrow alleys of the old town are crowded and suggests alternative sights outside the city walls.
It also plans to test a car-sharing scheme to entice tourists to explore the surrounding areas.
Barcelona is working on a joint marketing plan with the region around the city to get tourists to venture beyond the city's most famous sites such as the Saga Familial church or the Las Rambles boulevard.
"Barcelona is small but the destination of Barcelona is beyond the city and has a lot of attributes and attractions," said Barcelona Tourism director Joan Tortilla Rene.
Even New York City, across the Atlantic Ocean, has launched a campaign to encourage tourists to explore the boroughs beyond Manhattan and the Statue of Liberty.
It is also trying to lure more visitors during off-peak times in January and February, for instance, with events such as New York Restaurant Week and Broadway Week.
"That really helps give visitors tremendous value and helps us fill the slower periods," Christopher Heywood, a spokesman for New York City's official tourism organization NYC & Company, told Reuters.
The booming cruise industry is one of the biggest challenges for some cities.
In Dubrovnik, multiple cruise ships often disgorge thousands of passengers in one day, making the city's streets noisy and overcrowded.
The city is now trying to stagger the arrival of the ships and eventually to ensure arrivals are spread evenly throughout the week so that there won't be 10 ships coming to port at the same time.
Venice has drawn up new rules requiring big cruise ships to take a less glamorous route to the industrial port of Marghera, rather than passing by St. Mark's Square.
Some travel companies are also playing a role in the battle against overtourism.
Ctrip, China's biggest online travel agency, uses data to predict which destinations may be overcrowded and expensive and then offers customers alternatives that may be in less demand, Chief Executive Jane Jie Sun said.
"Consumers like it because they get the best value from their travel. Hotels like it because they can host all these travelers better. Airlines like it because they are not running to overcapacity on one route and under on another," she said.
Airbnb, criticized for its impact on local housing in popular tourist cities, said it does offer rural properties on its site, often in areas where there are no hotels.
"Tourism is only going to grow and by distributing over a larger surface area, you can minimize the impact," co-founder and chief strategy officer Nathan Blecharczyk said in an interview.
The UNTO has been working with universities on the problem of overtourism and plans to publish recommendations in a few months on how destinations can cope.
"You need a balance between growth, sustainability and promotion of destinations," UNTO Secretary General Zurab Pololikashvili said.
Gloria Guevara, president and chief executive of the World Travel and Tourism Council (WTTC), said destinations had to plan for the long term and create infrastructure that allowed them to direct tourist flows to stimulate local economies without overburdening hotspots.
"At the end of the day, tourism creates jobs, creates well-being and reduces poverty. But the benefits should be for everybody," she said.
The WTTC and consultancy McKinsey plan to work with six cities to try out various tactics to combat overcrowding.
