After days and days on this site, thanks to all the great advice, I have our trip almost planned. One disappointment is I just tried to get reservations on the Bernina Express frmo Lugano or Tirano and it appears to be impossible. Am I missing something? Reservations can only be made 60 days in advance and I put in almost 60 dates and kept getting "no seats available for that date." Can that be true? I went to the myswitzerland.raileurope.com site. I did notice that they started in St Moritz rather than Tirano. Could there be another site that would have seats available?
