Having been to both I’d choose Harrogate. And I hate Harrogate. Not uprooting to a new country? Tick. Title contenders and Champion’s league or relegation battle. Tick.
Been to Italy many times and love it but never to Naples and it was on my list until two friends came back from a 3 week driving tour around the whole country last week. They said the one place they hated was Naples, filthy from about 10K in to the centre. They were booked to stay for two nights but left after the first one.
I believe the ‘old town’ is ok but my recollection is it’s like driving through a third world shanty town. This was 20 years ago but it didn’t look like a place you could smarten up without an atom bomb. We abandoned our day trip. I would however highly recommend a fly drive trip flying into Naples. Hire a car, visit Herculaneum and pompeii, round the bay of Naples to the amalfi coast. Loads of great stop off places. One of the best holidays I’ve had once we reversed out of Naples and headed for sorrento. Driving on the amalfi coast not for the faint hearted
