we drove from Disneyland Paris down to Royan, near La Rochelle last year and couldnt believe the tolls we had to pay. This year we are looking at driving from Mont St Michel down past La Rochelle again to La Palmyre. Bought a new sat nav so hoping that will help, but wandering are there much tolls going in that direction? Probably could have planned it better - we are coming into Cherbourg but changed out minds as to where we are going but had ferry booked ....
