I am looking to travel from Barcelona to Cadiz on the 2nd of August and back on the 6th of August.
So far I could get reservations online for part of the trip on the Eurail site but for other parts it was sold out or not possible to reserve.
-So I was wondering if I could either book a ticket somewhere online for parts of the trip that I could not reserve? and what site you would recommend for this? I saw for example “Thetrainline’ but am not sure if I could trust it or if there are better sites.
-or how I could find a (regional) train that is not needed to reserve from Sevilla to Cadiz ( this part is the hardest to find reservations for)
