I've already booked my Venice to Salzburg bus/train tickets successfully (and cheaply!) thanks to the great information people have shared on this forum. I will wait to buy train tickets for Italy when I'm there, again based on information I've gleaned from these forums. And I have my Eurostar tickets, again at what I consider a bargain price, by following the advice here.
Now it's just occurred to me that maybe I should buy my Salzburg to Munich tickets in advance, too. I just checked the OBB website and it looks like I can purchase one-way tickets on June 28th for 34 euros each which can be used on any train that day. Can anyone tell me if I'm reading their site correctly? And is it to my advantage to buy the tickets now? My date is certain -- unless the volcano changes my plans completely. With that in mind, unless there would be a considerable saving by buying in advance, I'd rather not lay out any more nonrefundble money yet.
Thanks to anyone who has any knowledge of the sometimes inscrutable OBB website.
