The travel agency said that the small group has become a big group. Is it illegal not to write it into the contract?

According to Baidu Law Pro, if a travel agency turns a small group into a large group without writing it into the contract, then the travel agency violates the contract and infringes on the legitimate rights and interests of tourists. Tourists can ask the travel agency to restore the original state or provide corresponding compensation. If the travel agency refuses to perform, tourists can complain to the relevant departments or bring a lawsuit to the court.

Travel agency refers to an enterprise that organizes tourism as its main business and provides tourism services to the society. The legal relationship between travel agencies and tourists shall abide by the provisions of the Contract Law of People's Republic of China (PRC), the Tourism Law of the People's Republic of China and other laws and regulations.
