This is more of a general Paris question that's not related to DLP, so I hope that's okay. 20-yr-old DS and his best friend will be studying in Rouen, France for 5 weeks this summer, and they'd like to venture out on some weekend excursions from Paris to other countries, whether by train or by air. Anyone have any experience with doing this and any helpful tips?
They're trying to get things planned out ASAP because they leave for France on June 2.
Any advice at all will be greatly appreciated!
