Are there are companies recommended for a minivan holding approx. 8 from Le Harve to Paris, a tour of Paris with 4-5 longer stops, and then return to Le Harve to our ship on Sept. 20? We realize that we would only have 4-5 hours in Paris due to the long trip. Suggestions on where to spend the time? Or would using the metro or Ho Ho and a ship excursion to get to/from Paris be the best option regardless of cost differences?
