So we have updated our itinerary for what we hope is the last time.
Tuesday, May 15, we will arrive in Boppard around 8am. We are dropping our luggage off at the hotel and plan to explore Boppard for a bit before going to Braubach to see Marksburg Castle.
Thursday, May 17, we will take the train from Boppard to Bingen and then ride the KD boat cruise to St. Goar and then get back on the boat and ride it back to Boppard.
Friday, May 18, we will be taking an early morning train to Frankfurt. Our flight leaves at 1:10 pm, so we will have to leave fairly early in the morning.
What would be the most cost-effective way of getting around with this itinerary?
