Si - If you're looking for a nice beach holiday with interesting towns nearby, you could do a lot worse than Benodet, just to the South of Quimper on the southern coast of Brittany. Not too far to drive once you're over there, and not so far south that the heat is too much for the little 'un. We've been there 3 times. Once as kids when my parents were in much the same position, once with my own kids when they were young and for the same reason, and once a couple of years back with some friends. We hired a gite through Brittany Ferries, and when split between 4 couples with 2 cars, with a self catering gite to sleep 10, it cost us £225 per couple for the ferry crossing Plymouth/Roscoff including the gite for a week.
