carrying water on ferry

[yvoone]

we will be taking the ferry to santander soon. does anyone know if the car deck of brittany ferry's pont aven has heating?
i am just worrying if the water in my water tank will freeze as we will not be able to leave the van heating on for 22 hours while we are not allowed back into our van.
