SP26 - Another overnight stop

With the distance from home in Kent to the overnight at Dawlish Warren, it looks to be about 260 miles and nearly five hours on the road with no stops. 

The distances I have plotted in Spain and France are far lower than this. The plan is to arrive somewhere early enough to find space in the aire or on the campsite, and then be able to sit and take in the view or explore the town.

I wanted somewhere around halfway to break the journey, allow some stops on the way. On Search4sites I found Wyndham Farm. It's close enough to the A303 and also near to Stourhead National Trust.
