Tell us what the missus likes first.

Mine is a literary nut with an interest in ancient history, so.....
Places we visited, included: I took her to Hadrian's Wall and nearby Roman forts; plus Haworth with a walk to the ruin on the moors, that inspired the site for Wuthering Heights.

One assumes London will be on their itinerary, though not stated, simply as POE into the UK. Therefore unless Google Maps has really screwed up, Bath is significantly closer to London and Somerset than Clovelly. In fact, Bath is in Somerset.

I guess you haven't read all the OP's posts in detail - his mother appears to be living in, or very close to Minehead, which is about 42 miles from Clovelly and 56 miles from Bath.

Also, given that he is borrowing his mother's car, they are presumably taking a train to Minehead (or a bus or a taxi shuttle) but in any case between London and Minehead they will be carrying their luggage with them, so the scope for sightseeing between London and Minehead is very limited. Therefore the distance in the Micra is going to be the distance from Minehead, and that the OP and his wife might pass close to places south and west of London is largely irrelevant. And I wasn't suggesting that they shouldn't visit Bath, I was just noting that Clovelly is closer, though IMO Bath would be more interesting given a choice between the two.

Ah, my mind reading skills messed up again. So what you meant but didn't say is that Bath is further from Dunster.

Portsmouth, well, for a little history, Portsmouth dockyard is amazing, beaulei motor museum, new forest, Poole, Winchester, Winchester Cathederal.

Train to London, then all the london things, Covent Garden at Christmas is absilutely magical, they usualy have an xmas market, truly fantastic, although expensive, have many pictures if you'd like, St Pauls, and Oxford st is amazing, how about Hamleys (pointing out that Hamleys is older than the USofA is always quite entertaining).

Hope that will do for a start :-)

Forgive the tangent, but how have you managed to sort the insurance on this, as I'd like to borrow my parents' car, but haven't found a way of insuring it yet...

I'm a big fan of the trains back in the UK, no driving, good service and reasonably priced.

Here's a link to the various passes ,
Note , they are 20% off in winter.

e.g. You could get a 3 day consecutive pass for $129.

Lunch in a country pub.

When I went back 3 years ago, my Dad was able to add me as a driver on his insurance for little or no cost. So he said! (coverage was probably minimal, but at least legal). No clue which insurance co .

Trying to go up it, or rolling backwards down it?
