Due to insufficient applicants, the travel agency failed to form a tour group.

This kind of situation belongs to the contract dispute, which should be settled according to the contract in principle.

Because of the unfavorable clauses in the contract, the solution to the failure to form a group is to reschedule or change the route. As consumers, they should be cautious when signing contracts and have the right to request changes or refuse to sign unreasonable terms; Otherwise, if the terms of the contract are unfavorable to you, the lawsuit will be more passive.

As for the unfavorable terms of the contract, although you can say that you didn't read the terms carefully during the litigation, you can also say that the terms are obviously unfair, but how the judge determines them is still unknown. In other words, in the case of a lawsuit, both the travel agency and you are at risk of losing the case (if there is no such clause, you have the right to ask for a refund if you fail to form a group due to the travel agency, and the lawsuit will definitely win).

Considering that the contract is unfavorable to you, it is suggested to negotiate with the travel agency as much as possible and ask for a refund. If there is no refund, you can complain to the tourism bureau and the consumer association. Due to the fault of the travel agency itself, in this case, if the other party is afraid of wrangling, it may also refund your money.
