We plan to visit our son this Christmas holiday, who will be living in Limoges for 9 months. After a day or two of seeing his surroundings, we would like to go someplace for a week or so. A combination of culture, history and mother nature (and perhaps warmer weather!). Probably along the coast somewhere. We are a USA MN family with sons ages 20, 22 and 24. Sons speak French. Wide open for all suggestions. Any ideas?
