Thereafter, once you are back in Warsaw, you would have a chance to see how different the 2nd World War looked in this part of Europe. Such “double” travel during one holiday might be a great way to discover this complex history! Because of the fact, that nowadays there are plenty of flights from London to Warsaw, it will be easy to find flights for most convenient date as well as time (good site). As a result of this, such trip will be relatively easy to organize.
Another idea for different holiday is to visit Stockholm in order to attend as many festival as cultural festivals as possible. During the summer there are many events like this in Stockholm! There are big as well as already famous events (as for example Stockholm Film Festival), but also many small, not events in various parks and even on the street! It is not hard to find information about them online, so finding them will be easy too . Moreover, there are plenty of cheap flights Stockholm, so such trip can be really affordable and does not must ruin your budget, even if your budget is really limited. http://lot.com/airline-tickets/flights-to-stockholm
