Looking for advice please on which is the best ticket option on DB to get from Berlin to Bad Harzburg (Lower Saxony) (2 adults travelling together). The Schoenes Wochenende ticket is a great offer but on this occasion it doesn't work for us as we wish to have the possibility to take an IC/ICE train which is excluded from the Schoenes Wochenende ticket.
Is there any better option that the full price point to point fare. Any advice from experts on the DB ticketing system greatly appreciated (we have no discount cards, 2nd class travel is fine). Thanks.
