we would like to see Honfleur and are travelling from London. Is it a good idea to take the chunnel to lille and then rent a car and drive along the coast to honfleur? we are also hoping to see Giverny, Versaiiles and Provence. we have been to paris previously so we were planning only a few days there. we have 15 days of travel time. thanks so very much for any insights as to what might be best for travel.
