You can still book online if you don't know your vehicle registration or if you will be hiring a car. Simply check the box under the vehicle registration field on the Passenger Details step of the booking process. When you have your vehicle registration details, please add this information to your booking as this will avoid delays at the port. You can do this by choosing either the 'Manage Booking’ or the 'Log in/Sign up’ button at the top of the home page.
