Dear interrail website: I know what a seat reservation is! I know reservation isn't mandatory for this train! I want to reserve anyway, as you tell me I can! Why don't you give me a way to actually do it, *as you did earlier* when I wasn't sure the hotel would be able to print it? Oh, and also, I don't need more information because all of the "more information" is either irrelevant or I already know it!
