First objective:
Save you money on your vacation accommodation.
A practical case ...
Book 1 week's rental for a seaside vacation on the Atlantic coast with your tribe this summer!
The weekly price is 800 euros, set by the owner. To this must be added the tourist tax of around 40 euros.
By booking directly with the accommodation provider:
Cost of stay = 840 euros
By booking the same holiday on an online platform:
Amount of stay €800 + traveller service fee €135 (billed by a platform) + tourist tax €40 = €975 .
That's a saving of 135 euros with no travel costs.
