I am currently planning on taking about a week to travel by train throughout Spain. I have previously purchased a global railpass and now just want to make my train reservations however I have not been able to find a website online other than Raildude.com that would let me do this, before I arrive in the country. I am planning to go in May and am trying to prep beforehand. Raildude reservations are typically more than the 10 euro that all the railpass websites indicate is the regional fee for Spain and I am trying to not get ripped off while still making sure I get the trains I want. I know I can get reservations at the stations but am looking for the beginning of my journey to be reserved.
Also I do not want to have to pay full price for a normal ticket since I have the pass.
Current Routes I plan to take
Paris --> Irun --> San Sebastain
San Sebastain--> Madrid
Madrid --> Barcelona
Thank you for your help
