If you decide to spend your well-deserved vacation not in your mother-in-law's garden, but to admire the masterpieces of the Louvre, Prado or Westminster Abbey, then you need to start by choosing a tour operator.
You can independently engage in purchasing tickets, planning a route and booking places in hotels, but if you do not want to do it, you should contact a reliable tour operator.
But you should not contact the first available travel agency. You are aware that the travel business is quite a profitable thing, and many scammers and swindlers like to fish in it, just like in any other profitable business.
And, of course, you will not like it if you, having paid for two weeks of living in the Suite of a five-star hotel, upon arrival at the place of the palace, find the most ordinary hostel with combined amenities on the ground floor. A suite in it will be called a room, from the window of which a not too frank view of the trash heap opens.
But that's not the worst part. There have been cases when, upon arrival in another country, vacationers were surprised to find that it turns out that in Paraguay they will not be able to surf at all. For the simple reason that there is not only the ocean. But even the sea is not, and never was.
