I have been trying to book Paris to Munich for the morning of February 3rd. I've tried Rail Europe and Trainline. Every time I get to the submit payment page...I get an error message. Please advise. Some error message say their is going to be construction then. Should I just Fly instead?
I think you'll need to book your tickets using Deutsche Bahn (bahn.de) which will be a TGV + ICE train trip. I see tickets from 53€ - 73€.
