My family and I want to travel for 10 days in October and I looked at the InterRail pass that gives you 5 travel days within a 20 day period for a reasonable price. My question is.....Once I receive the pass from InterRail, do I then have to make separate reservations on each of the legs I want to take, or is it similar to the AB Swiss pass where you can just go to a station and hop on a train. If anyone has some experience with the InterRail, I would love some real world info.
