Hi!!
I am going to be traveling by train for 3 weeks this summer. Since I will have just finished a semester study abroad program, I will have a large suitcase with wheels (as opposed a backpack). Can anybody tell me if this will be a problem on RENFE trains in Spain? Where and how is it stored? Should I bring something to lock it onto the rack? Any advice would be great as this will be my first trip to Spain:)
