France First time with a Motorhome

Arrivakids

I am not sure if this has been asked before?   We intend to Travel to France again this year with our Motorhome , We have been the last three years in a Caravan . We know about the Aires Stopping at areas of Interest. Can anyone tell us what the Difference will be for us this year. We have looked at Ferry Crossing for around the same time as we normally go and it looks like the Price is more expensive with the Motorhome. . Plymouth to Roscoff .
