The tourism sector is changing very quickly : the tourism in general, the traveller and the holidays booking modalities are in continuous evolution.
The new tourists are more and more accustomed to organize their holidays by themselves, without the help of agencies and tour operators. And the hospitality companies have had to adapt to these changes.
In this sense nowaday it is fundamental to have booking engine on your website because it allows you to receive precious reservations. You don’t really want to risk that your potential customers book on an OTA that asks you for high commissions.
