I will arriving in Frankfurt on August 15th for a two-week tour of Germany and Prague, exclusively by rail. My itinerary is as follows:
August 15th: Travel from Frankfurt by train to Weinheim to visit Sichtungsgarten Hermannshof and then travel back to Goettingen that same afternoon. I will either visit the University of Gottingen botanical gardens in the early evening or the following morning.
August 16th: Leave Goettingen about 10 AM for Erfurt and spend the remainder of the day visiting Erfurt and Egapark. Overnight in Erfurt
August 17th: Take the train from Erfurt to Potsdam and visit the Karl Foerster Garden as well as the University of Potsdam Botanical Garden and the Sanssouci gardens, and then continue into Berlin for three nights.
The only side trip while I'm in Berlin that might not use the S-bahn system or local buses would be a trip to the Forest Botanical Garden Eberswalde on Sunday, August 19th. I will plan to use day passes for all of my other transportation needs in Berlin.
August 20th: Travel by train from Berlin to Prague with a 4-hour stop in Dresden. With a German Rail flexipass, would this be a good time to use one of my days? Do I need to purchase a separate ticket from the German border to Prague?
I will be spending three nights in Prague.
August 23rd: Take the bus from Prague to Nuremberg, store my luggage at the station, and then take a train to Erlangen for lunch and a visit to the Erlangen Botanical Garden. Then return to Nuremberg, do a walking tour of the city, and then continue by train the same day to Munich for three nights. Can I use the flexipass for the round trip to Erlangen?
August 24th: Purchase an entire network single day ticket to visit the Sichtungsgarten Weihenstephan in Freising.
August 25th: Purchase another entire network single day ticket to visit the Munich Botanical Garden, the Nymphenburg Palace grounds, the Andechs Monastery for lunch, and WestPark in the afternoon.
August 26th: Take the train from Munich to Bamberg for the tail end of the Sandkerwa Bavarian Folk Festival and overnight in Bamberg.
August 27th: Take the train from Bamberg to Wurzburg and spend two nights in Wurzburg.
August 28th: Make a day trip to Rothenburg.
August 29th: Take the train from Wurzburg to Frankfurt, visit the Palmengarten, and then continue on to Frankfurt airport for the return trip home.
Which of these of rail travel does it make sense to use a German Rail flexipass? Certainly the first day, yes? For the trip from Goettingen to Erfurt, German Rail offers a Regio 120plus Ticket for 22 Euros. Is this an advance purchase ticket only? Does it make sense to use a flexipass day for this trip?
There is a Sparpreis ticket available for the Erfurt to Potsdam trip for 29.90 Euros, but I will only have been in Germany for two days at this point and I understand that this type of ticket requires at least a three day advance purchase. Is this another good day to use the flexipass?
I think the next day I might consider using the flexipass would be the day I travel from Berlin to Prague, but only if the fare from Berlin to the Czech border is significant enough? Is it?
I will definitely use the flexipass for the bus trip from Prague to Nuremberg, and I understand that I will need a seat reservation for this.
The Sparpreis train ticket from Munich to Bamberg priced out at 33.90 Euros, so does it make sense to use a flexipass day here?
And the round trip from Wurzburg to Rothenburg priced out at 31.4 Euros at the Flexpreis rate, so does it make sense to use a flexipass day here as well?
So I think I'm looking at either a 5- or 7-day flexipass, with point-to-point purchases for Bamberg to Wurzburg, Wurzburg to Frankfurt airport, and possibly one or two other smaller trips.
Thanks.
