Thank you everyone for your input, it's really appreciated. Yes, we are tied to these cities and dates, it's part of a month-long trip we are taking and right in the middle. We are traveling with another couple and will be covering a lot of ground. I know it's early to book train tickets, I just wanted to make sure we were going to be able to get there at all, so, I was checking train, air and whatever else I could. We were also trying to put together a "budget", as best we could, anyway. The bus idea might be perfect, thanks, I will look into that. Also, the suggestion for Seat 61 is great, we have been looking into it. Sometimes you have to just surrender to a "travel day" and make the most of it as things can't go as quickly as we would like I guess. I really love this site, it has helped me to work thru things and the website information is so valuable! I had posted on another site under the countries we were going to because I didn't realize there was a "transportation" forum, probably more fitting for my questions.
PS: I went thru my notes from the travel consultant form RS and realized that he may have been talking about Germany for the "lander" tickets, we will also be in Salzburg / Fussen area, so, sorry about that. I had a lot of notes on a list and got confused I thinkg.
