In popular tourist areas well-developed infrastructure, which is why today, in many countries, tourism is one of the most important industrial sectors. As you know, three quarters of tourists are citizens of the twenty richest countries in the world and most of them prefer to travel to Europe or North America. However, according to recent data, more and more tourists are visiting and other parts of the world.
