I am travelling for the next week around Hungary with a 1st class Eurail pass and will use a number of domestic IC trains (such as Budapest to Pecs and to Debrecen).
Am I right that I must have a paid reservation to board these trains?
What is the best / cheapest way to book these?
I see I can book for close to $6 each through Eurail, likely less through Czech railways. Is it possible to book at ticket desks in Hungary, or even on the train? Many of these trains run frequently and I would like to leave it to the last minute to decide what trains to take (which is part of the point of Eurail….)
