After that, once you are back in Warsaw, you will have an opportunity to see how different the 2nd World War looked in this part of Europe. Such “double” travel during one holiday might be a superb way to discover such complex history! Because of the fact, that these days there are lots of flights from London to Warsaw, it would be easy to find flights for most convenient date and time (worth checking out). Because of this, such trip will be quite easy to organize.
Another idea for unconventional holiday is to visit Stockholm with purpose to attend as plenty of festival as cultural events as possible. During every summer there are many events like this in the city! There are big and already famous events (as for example Stockholm Film Festival), but also plenty of small, alternative events in numerous parks as well as on the street! It is not hard to find info about them online, so finding them will be easy too (news). Furthermore, there are plenty of cheap flights Stockholm, so such trip can be totally affordable and does not gotta ruin your budget, even if your budget is very small.
