We will be arriving in Frankfurt by train from Paris and will be departing by air back to the US in early December. This will be our first time in Germany. How many days should I plan to stay in Frankfurt? I plan on taking a walking tour of Frankfurt and just roaming around 1 day. Any suggestions for day trips/tours that we can take to see something other than Frankfurt this time of year, but are easy using Frankfurt as a base?
Thank you in advance!
