We're on the morning ferry to Santander tomorrow. If the fridge is on 'tow mode' and of course the car ignition will be off, what will happen to the fridge during the 30 hour crossing? Just thinking about ice cubes in the freezer, rather than what's chilling in the fridge itself.

Cheers.

Don't forget you can freeze bread,margarine,milk and cheese to use that valuable space.

Thanks all. Advise noted. The only perishables are our ferry food, which we'll take up to our cabin. Looking forward to the Spanish fruit, veg, wine, cheese etc. so not taking it from the UK. I'll empty the ice cube tray and make ice when on sites in Jaca and La Fresneda.

We use to only pack full with frozen goods, even Gin or Vodka in re-used water bottles ( Always a refreshing shock in the morning if you forget to label) then have part bake or flat breads (tortillas) make a great omelette roll with onions, chilli etc before 1st shop on landing

Connected to very poor WiFi aboard Brittany Ferries Baie De Seine (i'm not complaining by the way). On this ship, which sails under the 'Economie' brand, the caravans, motorhomes, vans etc. are parked on the open deck, and the majority of yesterday was blue skies, full sun and good temps. The Eriba was most likely pretty warm inside, so no chance of the fridge remaining cool for very long after I switched off the ignition.

Yes, our alarm went off. The beauty of being on the open deck is that you can unlock/lock the car from the sun deck, glass of wine in hand.

Colin, great thought. I'll enquire prior to our return.

With most VW group cars you should be able to disable the alarm. Look for a button on the 'B' post behind the drivers seat. Press the button, shut the doors and lock the car. The alarm is automatically reinstated when you unlock the car again.
