What if I want to change the itinerary arranged by the travel agency?

I am a staff member of the Changpo Sales Department of Hunan Xinkanghui International Travel Agency. After the promulgation of the new tourism law, if the itinerary is changed, if a unit is traveling as a group, the unit leader needs to agree and submit the request to the group agency. If you change the plan, after confirmation, the organizing agency will issue a paper confirmation letter to the local pick-up agency, and then the tour guide can implement it! Individual travelers need to sign and approve it from all members of the group!
