The plan for our Rhine cruise day (a Saturday in May) was to buy a R-P Ticket, take a train from Bacharach to Bingen ('left' side of the Rhine?), K-D cruise to Braubach (20% discount), take a train upriver on the right(?) side of the Rhine to Rudesheim, ferry across to Bingen and then train back to Bacarach. All this over the course of the day with various stops along the way for places of interest. The thought was that the R-P ticket would cover all the train travel.
BUT...I just noticed that the eastern bank of the Rhine is actually in Hesse.
So it would appear that we will need to buy a R-P Ticket and a Hesse Ticket if we want take a train down the right bank after the boat tour. Yes?
