I need to book some trains.
Main question: ******Saturday September 16 Bacharach to Mainz to Basel to Lucern found what I want on DB site - book on this db website ? ************ want to lock this part up today if so bc they have what i need and the price seems good at 79. in reading I've seen a lot of things about extra fees, certain codes to use, websites not to use etc.
other questons
What website is best for me to book the following and please tell me any tricks. I have seen workarounds for raileurope and have been told not to trainline-sncg.eu. (though these site might just apply to other parts of my trip) and some said said to use en.voyages-sncf.coom Please also tell me if these assumptions are true below
1) dropping off rental car and going Mainz to Bingen one way - can just book this at the station - want to catch KD boat - can buy KD boat at the dock
2) One day will be using the train on the Rhine to get around fm Bacharach to see Marksburg Castle then to St Goar to see that castle and back to Bacharach and if any extra time and you think worth it may drop by Oberwesel but will really be one day (and a half a day the day before which I will just purchase fare as needed bc won't be going a bunch of places ) For the full day to multiple cities thought the Rheinland-Pfalz Ticket would save?
I can just get these tickets for these trains when I am there no need to buy ahead?
thanks in advance
