Lucii, I think North Devon would be a better place to stay than Mid Devon, as there's not much to do in Mid Devon and it's approx an hour’s drive to the seaside. We do have Exmoor in Mid Devon which has some lovely B&B's and beautiful countryside, so it might be worth while seeing what is available on Exmoor.

But if its long walks on the beach you're after, I'd go to North Devon if I were you. I think or Croyde or Woolacombe are both nice areas. Check them out on the internet.

Saunton Sands is a really nice hotel but it's sooooooooo expensive!! Perhaps you could get an autumn deal?

Good luck.
