Hi Faith,
I drive.
Living in Basingstoke, I don't have to worry about the Red Funnel ransom!
The ferry over the Channel is not too bad; I uses DFDS to Dunkirk and, if you choose the right time, the cost is not so bad, although it was a lot cheaper when it was Norfolk Line.
I have probably spent as much time driving on the "wrong side" of the road as on the left so that doesn't worry me.
And of course, having my car with me gives me a couple of advantages; I can get from one place to another quickly and I have somewhere to hide from the weather and keep warm!
In fact, I am thinking of going this week; Friday & Saturday's forecast are showing clear weather, with some sun. The drawback is the wind chill, down to -7C!
Cheers
Kelvin
