Colin,
We went to La Yole last year and enjoyed it so much we re-booked for this year.
Although a different site to the one you have booked the area in general is lovely,
the beaches are golden sand for mile after mile, there are plenty of supermarkets dotted around the place and it is excellent for family cycling as there are plenty of cycle paths. Were planning on taking a fair bit of food this time as the cost of the euro is not particularly good at the minute.
