April 18: train from Amsterdam to Cologne—spend the night in Cologne
April 19: train to St. Goar—K-D boat trip from St. Goar to Bacharach with senior discount?—train to Mainz—spend the night in Mainz
April 20: train to Nuremberg with 2-3 hour stop in Rothenburg (RS suggestion)—spend the night in Nuremberg
April 21: train to Prague-spend 2 nights in Prague (April 21, 22)
April 23: train to Vienna—spend 3 nights in Vienna with day trip to Bratislava (April 23, 24, 25)
April 26: train to Budapest, spend 5 nights in Budapest (April 26, 27, 28, 29, 30)
May 1: early AM flight to US
I am booking hotel stays in the cities as outlined above using reward stays so not really asking for input in that regard although somewhat open to tweaking the way I have nights allocated. (e.g. better to take 1 of the nights in Budapest to stay in Rhine Valley longer or is the way I have it planned OK?)
I do need help trying to figure out the easiest and most econimcal way to manage the train and Rhine boat transportation for this itinerary. We would enjoy easy biking options if feasible here and there.
Background--my husband and I are in our 60's and in good health. Not overly interested in historical sites but more focused on people & scenery with a mix of small towns and larger cities.
