"Rail Europe is a marketing organization and really not a good source for buying tickets. And rail passes - in most instances - are not a good deal either. Your best bet is to buy point-to-point tickets. These you can get in Europe at the station on the day of your departure. This way you can take advantage opf the many discount ticket opportunities. For example, day tickets in Bavaria to anywhere in Bavaria can be had for EUR22 for one person, or EUR 28 for up to 5 people travelling on the same ticket.
Otherwise, go to the websites of the individual country RR companies and order your ticket(s) on the Internet. "
I think you should google more about this company and see where else you can book the tickets.
