Prague is such a fairytale city that it is impossible not to fall in love with it!. It is perfect for a weekend, as it is only 2.5 hours flight-time and there are plenty of great offers to visit it. Summer is probably the best time to go there as you can just stroll along its cosy streets and take a boat trip on the Vltava river. Forget about hen and stag nights: Prague is made for loved-up couples! ;-)
