I have a 1st Class Interrail Global pass and want to reserve a seat on ICE9574 between Strasbourg and Paris. Neither interrail.eu nor Rail Europe offer it - they only offer 2nd class seats.
However, this train starts from Stuttgart and 1st Class seats CAN be booked from either Stuttgart or from Karlsruhe to Paris - so there are very definitely 1st Class seats on the train that are available between Strasbourg and Paris but for some reason the booking engines do not allow a 1st Class reservation from Strasbourg. (Rail Europe doesn’t even allow a 1st Class ticket to be purchased from Strasbourg!)
Is it legitimate for me to make a reservation from Karlsruhe to Paris and simply get on in Strasbourg? Can anything go wrong if I do this?
