Hi Heather, great tips and yes, we get snacks, drinks, toys, games etc. The drive itself is not really a problem – we have been doing this sort of thing with them since they were very little, and gameboys work a treat – the old version so that if we lose it, who cares… goes on every trip!! They get fed up & it gets more difficult when they know the end is near and we fanny around trying to find somewhere to stay or are lost, and when they are getting tired and grissly before they fall asleep… or when they fight!!! We have done the route from Bilbao to Malaga already, though not the return, and they were brilliant….. thank goodness for that Mcdonalds chain!!! Last time they were ‘sea sick’ and ‘car sick’ at the start, but they still want to go for it again. Tough little nuts really! We have to be near the port for the return sailing and don’t want to risk a non-stop trip through the night – we would rather plan to be there well ahead of time and stay overnight, not for the kids’ sake, but for ours!!?? Thanks for the offer, but 3 & 1/2 hours is a little bit too far.
