I bought an interrail pass to go from Brussels to Spain and Portugal and to be able to move easily without too much planning. The first destination is Valencia. Unfortunately, I see on the rail planner that there are not so many connections, and of the connections that there are, most I cannot reserve through the railplanner app and it does not clearly say how I can.
I just discovered this forum now, and I am a bit lost in all the information here (like, I can book reservations for french trains through Deutsche Bahn?). Any help would be appreciated . For now the best plan was taking a bus to Paris, because I assumed there were no bookable trains left because the railplanner app does not show them. But apparently there might be trains that aren't shown in the app?
Where/on what website/… should I check for trains, and make the reservations (Brussels-France, within France, and France-Valencia)? I can go to the international SNCB offices in Brussels South station tomorrow, if that would help.
Lots of people here seem to suggest that an interrail pass in France, Spain and Portugal might not be worth it, I can also still consider asking for a refund for my ticket.
