Read this article from the Telegraph and let me know whether I have left it too late! The author says that Prague has been taken over by lager louts, etc. Evidently the cheap flights from the UK mean that there is a new type of tourist in Prague: stag parties. http://tinyurl.com/4qmx8 Note: you will have to register (free) to see page 2 of the article.

Any other places that are similarly interesting and relatively undiscovered?
