We leave on 4/30, and will spend five nights in Paris before the tour starts in Chartres on May 6th. This is not a train strike day, although they are doing work at Montparnasse station. The result is that the usual train service from Paris to Chartres is curtailed. We have to take a three hour train trip from Gare Austerlitz to Chartres, instead of the more typical hour nonstop ride from Gare Montparnasse.
After the tour ends in Nice, we will spend two additional nights on our own. Train tickets are booked from Nice to Paris on Sunday May 20th (luckily not a strike day). We will spend two additional nights in Paris, and a night outside Dublin before flying home.
Looking forward to the trip.
