"It's such a delicate balance between being welcoming and also making sure you control the volume of people," says Anne-Marie Grosz, editor-in-chief of the International Journal of Tourism Research, based in Paris. She says that many host hotels are unwilling to deal with large crowds of tourists who have not been adequately briefed about the laws of the land. The French government has set up a hotline for people to report illegal behaviour or to report an altercation. "We will not tolerate people trespassing or breaking the law," said Interior Minister Manuel Valls.
In France, the number of "traveller crimes" has risen in recent years. According to the Paris prosecutor's office, there were 2,056 offences against foreigners in 2011, compared to 1,966 the previous year. "The main problem we are seeing is the surge in visitors visiting Europe, particularly France, Portugal and Germany, who are often mistaken for new arrivals," said Mr Nick, a consultant at the Campaign Against Living Miserably. "They are often seen as a nuisance, but don't seem to understand the greater risks they pose to local communities." A spokeswoman for the European Commission said there was no legal obligation for travel agencies to keep guests informed of possible security risks. "There is no obligation for travel agencies to inform travellers about the security procedures for their destinations, nor to inform travellers of any additional security checks they may have to undergo," she said. Passengers are advised to monitor the website of their travel agency for updated information, she added.

"The CAA is especially concerned that some travel agencies are not taking the necessary security precautions when offering services to foreign visitors. They can also lead to fights and violence, especially when the numbers are too large. According to the World Health Organisation, more than half of the world's population is now under the age of 15. A 'bathroom problem' In a survey by the charity End Violence Against Women International (EVAW), one-third of the more than 6,000 women surveyed said they had experienced some sort of harassment in public.
But the figures are higher for men - with some 600 men taking part in the survey. "In public spaces we have to be careful and take care of situations that are inappropriate," said study author Dr Sonia Delia, who works at the University of New Mexico in Albuquerque. But in the case of a Hong Kong event, visitors often come to Hong Kong to enjoy the sights and the sounds of the city, not to visit the local government offices and the local restaurants and shops in the touristy areas of the city. Tourism officials told a local broadcaster that they had received a total of 5,000 phone calls and emails in the past two days. The complaints came as hundreds of people lined up on central Hong Kong streets to get into the opening ceremonies of the World Cup.
"I have gone to the hotel where I am staying. I am staying at the Shangri-La hotel. There are thousands of people here and I have to queue to get in," said a woman surnamed Chen, who was queuing at the Shangri-La hotel. She said she had been unable to book her room for three days. "There are thousands of people here who want to get in. In Paris, visitors to the Louvre were told to stay away for around 24 hours last weekend, after out-of-control crowds turned the landmark into a 'concrete jungle'.
Major museums in London, Amsterdam, Paris and San Francisco are all planning similar measures in the wake of the Paris attacks last week. The challenge is to prevent such outbreaks before they happen. Places with a reputation for being hospitable to foreigners also tend to be popular tourist destinations.
In New York, for example, the number of tourists from Asia has increased by 40% in the past decade. But the city's reputation as a destination for tourists is largely a function of the fact that it has an international airport, the Manhattan Island, and that many of them arrive by plane. The american city has also witnessed a decline in the number of its own citizens who are foreign-born.

The number of New York City residents who are foreign-born has fallen to 16.7% in 2014 from 18.
In the UK, the government has tried to tackle the problem by restricting the length of the queues at many tourist attractions. But the ban itself has given rise to a new kind of tourist, more often drawn by the glamour of a spectacular city rather than the practical charms of a country. In recent years, this group has grown dramatically, with the number of foreign holidaymakers being estimated at around a million people a year. One of the most striking features of these visitors is that they seem to be of a distinctly different sort to those who have been traditionally drawn to tourist destinations. They are the so-called "gainfully employed" and they are not the sort of people who are used to being let in on a Sunday morning at 9am.
