I am taking an AMAWaterways River Cruise (solo travel) in July ending in Budapest (first visit). The boat gets there on Friday, we spend the day touring then disembark the next (Sat) morning. My flight back to US isn't until 4pm on the following Tuesday out of Frankfurt. I am looking for advice on how to best use the 3.5 days. Ideas:
1) Return to Frankfurt after cruise, rent a car and drive the Romance Highway south of Frankfurt. I rode my bike on that road many years ago as a teenager - sort of a nostalgia trip.
2) Stay in Budapest until Tuesday morning, fly back to Frankfurt then home.
3) Take an afternoon flight to Prague giving me 3 nights and 2 full days there, fly back to Frankfurt Tuesday morning.
4) ??? Open to suggestions.
Thanks for any and all help!
