Right mate, on the way out you might want to drive down the N154, a lovely road ( a number of us use it all the time). Then you could take the A12 towards Dreux and stay at the camping municipal at St Remy sur Avre. Tip - you cannot turn left across the traffic to get to it. What you do is turn right and go around a small traffic island so that you face across the main road and wait for the lights to change. Cross over and take the first right turn (about 30 metres) and follow the camping signs. The people who run the site do speak English, so once you have shown them your passport to check in they will look after you. If you don't want to cook walk back towards the village. When you see the kebab shop turn left. About 100 metres along on the left is an excellent pizza restaurant, where you can also buy wine by the jug, always a lot cheaper way of buying wine in French restaurants and perfectly quaffable. There is a bakers shop behind the village square on the opposite side of the road for fresh croissants, baguettes, pain au raisin, pain au chocolat (I'm dribbling now) - you will enjoy it. There is also a small Aldi type supermarket there for emergencies like jam and toilet paper (you must use French stuff as English toilet paper contains dodgy chemicals in it (most French sites do not provide toilet paper).
Cave Cooperartive du Vendomois, 41100 Villiers sur Loir, out in the coutryside. Open Tuesday-Saturday 9.00-12.00 and 14.00-18.00. One of the places that I found in the guide 'The vine art of plonk' (advice about how not to buy from expensive chateaux). If you visit, I suggest you ask to taste some of the cheaper wines as some of these have often won medals and I think taste better. If you don't like - don't buy. Try the Charme aux Dames fizzy too. You can pay with a debit or credit card. Right that's the wine done.
On the way back, you might give Camping Sainte Clair at Neufchatel-en-Bray a visit. At this site you order croissants, baguettes and pay for them as you register. You collect them in the morning. They normally also do food in their restaurant in the evening, not fancy but wholesome. There is also a large supermarket nearby for self catering and chocolate.
Lastly, to use a credit/debit card in France, whether for buying petrol or in a supermarket, you must press the equivalent of the green button first before entering your pin, then press the green button again afterwards. I have had to explain this to desparate Brits several times trying to fill up at un manned garages. That's all for now. Bonne vacance.

By the way, both the sites mentioned have electric hookup if you need it.
