Our Viking River Cruise ends in Nuremberg Germany on April 23, 2011 and I need suggestions on recommended travel ways to get to Paris. Should we just try to buy 90 days ahead of time the fastest train seats available? Any discounts out there for the train first class seats? Anything we should try to see along the way to Paris? We have 4 nights in Paris leaving for home on the 27th of April........Thanks for all helpful comments........Ricky
