Check that the person entitled to offer a room formalises his authorisation and the reason of the
complimentary on the reservation document prior to the guest arrival.
The complimentary can also be stipulated in a contract: tourism contracts, notably, should clearly
specify the number of complimentaries granted per rooms sold and indicate whether the breakfast or
the half-board is offered. The invoicing procedure for group courier (drivers and tour leader) should
be specified.
