I'm planning a trip June and will be flying into Heathrow. I would like to take the chunnel to Calais, France and then rent a car and begin a driving trip along the normandy coast, through the Loire valley to Beaune. We arrive in London about 10:30 AM on a Saturday. Should we plan to spend the night in London or is it fairly easy to get to the Eurostar train station? I'm not interested in renting a car in London as I don't want to deal with the traffic. I'd rather rent a car in Calais if possible. Has anyone done this? Does the Eurostar stop in Calais? Any advice would be appreciated including which towns to spend my 6 days while in france.
