After a short discussion we've decided we will aim for the Dordogne and find out what the area has to offer.
We had been a bit reluctant to go in that direction after stopping in a hotel in Sarlat many years ago.
We went by car, long before the MH, one June and it rained chats and chiens for the 7 days we were there – the hotel ran out of umbrellas they were providing for its guests by mid-week.
What with the rain, and every meal having a canard theme, we held strong views about the area but we will finally try once more.
There is an article about the Dordogne in MMM this month, mine arrived yesterday, and it gives a good insight to the area and a trawl with Monsieur Google's help, and Barrys input on here, have helped us decide.
Thanks for all your input – very helpful.
