I've just been on the 2 week western Europe trip and it's been an amazing experience. Our tour leader Jess was fantastic, and sorted out any issues we had with transport etc so that we didn't have to worry about anything. We got to see so many iconic sites around Europe (although it was very hot), and the included activities were good too - I liked the Murano and Burano day trip in Venice. Overall the hostels we had were fine, some much nicer than others, but nothing shocking. Sometimes the number of people sharing a dorm was uncomfortably high. I'd recommend a Euroventure tour to people who, like me, haven't travelled alone before, because having a tour leader like Jess and a lovely group of people to travel with makes the whole experience much easier.
