I would like to travel from Barcelona to Alicante or Elche on December 24 using a Eurail Pass. I have the following questions:
For trains like the Eurostar, I was able to check seat availability on the Eurail website even without purchasing the pass. However, for the route in Spain mentioned above, it seems like I can only make a reservation after obtaining the pass.
If I purchase the pass but there are no available seats, the pass would be useless. Therefore, I would like to check seat availability in advance. What is the best way to do this?
