Will adding a roof box, or putting bicycles on my roof change the price I pay?

Yes - Any vehicle over 1.85 meters in height, and vehicles with anything on the roof, will be unable to travel safely in the two storey section of our shuttles, so will be allocated to the single storey section. The price of a space in the single storey section of our shuttles is sometimes more than the price of a space in the two storey section.
