Trying to help friends with a train question. They are making a very quick trip trip to Bavaria, then need to get to Paris. Original plan was to drive to Munich to turn in the car, stay overnight, and catch the early morning fast train to Paris. They will be leaving Mittenwald after doing a castle day, arriving in Munich too late in the evening to really do much of anything. This now looks like just another one night hotel change and the hassle that involves. They are now thinking of staying another night in Mittenwald to allow them a little more relaxed time and just driving on from there to Paris.
They don't mind driving and aren't too concerned about a drop off charge. Part of the reason for taking the train in the first place was for their grandchild to have the train experience. My question: Is there an alternative place in Germany on the route to Paris that would be a good place to turn in a car and catch a train? Someplace that has multiple trains so there's not so much pressure to get there by a certain time or miss the train. Or would it make sense to drive to Munich after a second night in Mittenwald and take something other than the very early morning fast train? They just need to get to Paris by late afternoon. Thanks for your help!
