Cheap travel in Europe
In Poland and Europe, you can work and travel at the same time during your holiday breaks. Here, students simply pack their backpacks and set off on their way. This is a very popular form of sightseeing called "backpack" by the natives.
Due to the freedom of movement within the Schengen area and the presence of cheap airlines in Poland (Wizz Air, Ryan Air), city breaks, i.e. weekend trips to other cities in Europe are ever more popular. It is a great and inexpensive way to visit Europe.
