We are ending a trip to France with several days in Paris. The original plan was to drop off our rental car in Saint Malo and take the TGV into Gare Montparnasse. Unfortunately, the day we go to Paris is also a rail strike day. We could wait and see if the strike ends. One concern is that if the strike continues and our train is cancelled, at the last minute can we extend our Europcar rental? If we can keep the car, we could drive to a Europcar dropoff outside Paris and take the RER into the city, but we believe the RER trains are also impacted by the strike. Another option is to drive into Paris and drop the car at Europcar at Gare Montparnasse and then take a quick metro ride to our hotel near St Michel. We've briefly driven in Paris several times in the past, but we expect traffic during a rail strike will be daunting.
Realizing that none of us possess a crystal ball that can predict what will happen with the strike, we're just looking for suggestions, feedback, options, etc. Many thanks for your help.
