The fact is that a tourist can sue a company even if all tour conditions were fulfilled. For example, for failing to provide complete information about the resort. The author knows of several cases where one married couple turned this form of 'earning' into a regular practice.
The technology is simple. It is based on the principle: 'You can find fault even with a telegraph pole.' After booking a tour with a small or startup company, a nice-looking married couple flies to the resort together with other tourists. During the joint vacation, they deliberately seek out various discrepancies or inconsistencies with the contract between the tour operator and the client. These could be, for example, hotel room windows facing west instead of south, an interpreter's accent, a changed currency exchange rate in the country, or something along those lines.
During the tour, an appropriate mood is created among the group of vacationers. The most malleable ones are openly explained the advantages of expressing collective discontent, while the rest follow the principle of 'why should I be worse.' Thus, a collective complaint is prepared.
Upon returning home, all this is placed on the tour manager's desk, and he is given a choice: either settle the issue of moral damages 'amicably,' or the court and the Consumer Protection Society will deal with the company. In the worst case, this couple fully compensated themselves for the cost of the vacation or got another tour for free. In the best case, they put a tidy sum into their account.
Fighting such a trend is practically impossible. Therefore, large tour companies are already creating databases of such tourist racketeers.
