Booking trip for my parents, their tour ends in Prague with 10 days left to explore Germany during Oktoberfest (simply a coincidence).
1.Prague - Munich transfer
2. Munich
3. Munich
4. day trip to Neuschwanstein Castle - (suggest tour company)
5.Nuremberg
6. Nuremberg -day trip to Bamberg
7 Nurenberg - day trip to Wursburg
Do people manage to visit both towns in 1 day or it is better to spend day at each town?
8. trip to Rothenberg and return to Nuremberg? or not?
9. transfer to Frankfurt
10 Frankfurt
11 Flight home

I am also deliberating whether to book 2 nights in Frankfurt or just 1 and to spend additional night in Nuremberg to visit Resenburg. My parents wouldn't have a car and I am trying to organize everything so that they do not have to carry luggage with them as much.

Another option, perhaps to go Prague - Resenburg (overnight?)-Munich

For hotels - I will be using SPG points or priority club points except if I book 1 night in Rothenberg.

Please critique this itinerary.

At this point I am puzzled by train transportation in Germany as on some routes people suggest buying 2 separate regional tickets, or mention cheap offers which I do not understand how to find and book.
