'''1. Derived Prices'''
Booking.com can auto calculate different occupancies from one standard rate. This rate is either for the base or for the maximum occupancy of a specific room. The system then automatically adds or subtracts a percentage price per person when the occupancy increases or decreases. Since Booking.com needs a room price for the maximum number of guests it is best to set the standard rate as a room price with maximum occupancy and let the system subtract.
Ask your Booking.com rep to set this up.
