Our plan is to arrive in Stuttgart and then take a train to Rothenburg for the night, then return to Stuttgart the following day. After a couple of days in Stuttgart we'll head to Munich for Oktoberfest. Then after a couple of days there we'll move on to Prague.
That makes a total of four train trips.
Prices for four day rail pass w/ Prague extension is about $500 total for the two of us.
If I price out direct routes via bahn.de, I get two options for Prices. "Savings Fare" and "Standard Fare". Savings Fare is usually around half of standard fare. If I use all savings fare's, the total for the two of us comes to about $250 for all the trips. That's quite a savings versus the rail pass.
I understand that "Savings Fare" dictate that we must take a specific train. Outside of that, are there any other things I should consider about the Savings Fare before I purchase our tickets. Is there a reason why I should still consider the Rail Pass?
