I purchased this ticket on several occasions when I had to travel for long periods of time (over 3 hours), and it was extremely useful for traveling in Europe, where train delays are common, as it allowed me to change lines flexibly. I highly recommend it for people who want to enjoy a flexible trip with a personal plan rather than a tour from a travel agency.
