The capital city of Poland is an Alpha-Global city and the fastest-growing city in Eastern Europe. People from all over the country and continent flood into town for the weekends to take advantage of the food, the shopping, and, oh yeah, the intense nightlife, so you are sure to have an epic Warsaw hen weekend. The fact that Warsaw is so hopping now is pretty incredible, because this is a city with a harsh past. Almost completely destroyed in WWII, Warsaw has managed to retain or restore architectural bits and pieces from every epoch of its history, all the way back to the medieval Old Town - but it's also characterized by Eastern Bloc architecture, and has a more recently developed contemporary European vibe with its sky-scrapered skyline. 25% of the city is greenspace, so there's plenty of lounging room to take breaks between beers and seeing sights on your Warsaw hen weekend.

With a few months pre-planning, Ryanair and Wizz Air can take you from London to Warsaw for between £20-£30 (and Ryanair has flights out of Manchester, Bristol, Birmingham, and Liverpool, too, so you've got no excuses). The flight only takes about 2.5 hours and then there you are, in the middle of a bustling metropolis. There's one ticket for all kinds of public transport (just remember to validate it when you get on the first bus/metro/tram of a journey), and taxis are pretty easy to deal with (just call them rather than hailing them to avoid serious fleecing). All the major sights are within walking distance of one another, so once you get to the centre, you're golden.
