Please answer the case analysis of tourism laws and regulations in detail.

1) default. When traveling in Beijing, it is agreed to arrange a car, but passengers are allowed to return to their residences. Did not visit as agreed.

2) There are two natures:-> If the refund agreement is stamped with the official seal of the travel agency, Zhou's statement that the refund agreement is invalid is invalid.

-& gt； If it is not stamped, it has nothing to do with the travel agency. You should ask the tour guide for a refund.

3) It depends on the information brought by the passengers. If the refund agreement has the official seal of the travel agency, the quality supervision shall order the travel agency to refund the compensation to the passengers.

The above is purely a personal opinion, I hope it will help you.
