Stopover site - Calais to Biarritz

We are travelling in a motorhome with 2 children to Biarritz via the Eurotunnel to Calais mid August returning beginning of September.  We normally stop overnight at Calais and make the long 10 hour trip down to Biarritz in one day.  For medical reasons, we are unable to do that this year. Can anybody recommend a good convenient stopover site to break up this journey.  Would prefer a proper site rather than a municipal one.  I don't have a copy of the Tourer guide which a lot of you refer to unfortunately.

Thanks.
