France done differently (for us)

We have been to France many times, tenting and caravanning. This is a first for us.

My father in law (87) wants to do the tunnel, I have looked and looked for a campsite with B&B for him, not had much luck here in the UK and in France, I also looked at a Premier or Travel lodge around Folkestone and a day trip over, so he could experience it.

I came across Eurocamp doing short breaks 3 nights in a mobile home, with deck, sleeps 4 adults at Le Bien Assise for a lot less than I could do something similar, if I could find accommodation for him, and us in the caravan. We have stayed there many times as an overnighter or a few nights to finish off a holiday. It is France solo, no caravan, minimum in the boot so we can stock up, for return trip. Not restricted to towing speeds and hopefully the M25 car park will not be in operation for our out and return trips? Purchased my breathalysers from Halfords, had to get an extra Hi Vis vest for him. all set and ready to go?
