Thanks for the informative Reservations section.
RailEurope.com has no reservations for around May 17-31 for Rome to Madrid (via Nice>Barcelona) (& Berlin to Florence).
Anyone know what to do next? I don't want to be stuck w/o a train. I can reserve the others. (seems like most trains have that R in the timetable)
I suspect because they want $, RailEurope may be up to something, but I'm not sure. Thanks!
