I’m going on the European pathway tour this fall and have a question. I know the size of luggage but is it best to bring a backpack or an actual suitcase. I have a nice size backpack but not sure what’s better… Staying in hostels starting in London. What are your thoughts? Also staying at the wombats hostels, stupid question as I have never stayed in a hostel, Should I bring a sleeping back or a sheet or something.
