I have been trying to make a required reservation on a train, but I keep getting this message:
Prices unavailable
No price results were found for this connection. It is possible that all pass holder seats are sold out. Please try searching for another connection or check 'More information' and try other ways to book this seat reservation. If no pass holder seats are available anymore you need to buy a separate full fare ticket to board.
It says "If no pass holder seats are available ...". Does this mean that there are only a certain number of seats allotted to Eurail Pass holders, even though there may still be seats available on the train?
