Due to Jon's work we could only have two weeks for travelling and so this limited the number of countries or cities we could go to and their distance from each other - in the end two weeks was the perfect time for us.
Deciding the countries and cities was a little tricky to start with as we had loads of places we wanted to go including Poland, Germany, Italy, Switzerland and Hungary to name a few! After looking on the InterRail website and establishing which countries were close to each other, and the time it would take to travel by train between cities, we were soon able to narrow down our selection. We also thought that some cities and countries (Italy and Switzerland) could be visited on other holidays and might require more that 3-4 days when visiting. We wanted a few days in each place to really get a feel for the areas, I wouldn't have felt like I had really visited a place if I only went for 1 day.
Jon was really keen to visit Berlin, I had never been to Germany before and so was more than happy to go there for our first stop. Jon was also keen on Prague and as it was just under a 5 hour train journey from Berlin we confirmed that as our next stop. Vienna was somewhere I was keen to visit for a few days and so this was our third and finally Budapest (somewhere I had really wanted to visit) became our last stop and boy was it a good one! These cities had great train connections and linked really well for our trip. Something to note is also the train station you are arriving or departing from, as some of the cities have more than one and they can be a long way from your accommodation.
Overall I would really recommend InterRailing if you are keen to travel to a few places and I would highly recommend the cities we went to if you like history, culture and a night life. The website is clear and informative and when we were away it was super easy and smooth to travel to where we needed too. Maybe next time we will try a sleeper train!
Have you been to these countries or InterRailing?
