Do you charge per person or per vehicle?

Our online quote prices for airport transfers or point to point transfers are based on the number of passengers travelling + travel distance + time of travel, not per vehicle. However for wedding Transfers where people hire specific vehicles on an hourly basis then off-course we charge per vehicle .
