My husband and I are going on our first river cruise at the end of March, Regensburg to Budapest with a Prague add-on at the beginning. The Regensburg stop offers two excursions we're interested in: Historic Nuremberg or Munich Highlights. Any thoughts on each of these? They both cost about $300 per person. We tend to like museums and history, but we do also like the energy of a city. We like the structure that excursions offer but we are in our 50s and fairly mobile, and don't want to be held up too much by waiting for the group, if you know what I mean. $300 per person is an expensive addition, but I've read a lot of warnings about the challenges of booking a third-party tour, which might not be any cheaper anyway.
We've been pretty slow with our research, so I welcome any thoughts about Danube cruises and our stops in Regensburg, Passau, Krems, Vienna, and Budapest.
