I have been to Paris many times, but this will be different. We have 6 people traveling together, 3 generations, on a budget of about $300 per night. I would normally stay in the Marais or St. Germaine, but, we will have 2 cars and a fairly small budget for Paris. We are thinking maybe it would be better to stay somewhere on the outskirts, near a RER station, at a hotel that we can park our cars for free and train into the city. Ideally, we would be able to walk to good, authentic restaurants as well. Any great ideas out there?
