If you’re going that way then visiting some country pubs for an overnight stay is a fantastic experience. A lot of them have gone sort of gourmet but it’s more the atmosphere that’s memorable.
@VPS may have some good suggestions
If if you make it as far west as Wells, I would thoroughly recommend the Ancient Gatehouse hotel with full window views of magnificent Wells Cathedral right in front of you.
The ancient town of Chester is another good option which is more on your route.
Small town pubs are great; the smaller the better. Watch out if staying at larger towns or a city as parking may be very difficult.
