Due to the advertising and promotion tasks carried out by ATA, the Association receives a large number of requests to arrange authority to let. All these requests are entered into a data base and then forwarded to all the members of each village or town directly affected by the request, whether it is a private individual, travel agency or tour operator.
These requests are replied to directly by the company involved and all the information requested is sent to the client.
