In the same situation but looking for New Years Eve –
I’d recommend
Amsterdam (some ppl can get snobby but theres something for everyone, hiring bikes is the way forward, best way to get around to check out the pron, drugs, culture etc, but seriously you can t go wrong here)
Prague (a beautiful place, again lots of bars, things to see and do – did a 6 hour walking tour, sounds long but turned out to be one of the best things I’ve ever done whilst away, pretty much a perfect destination that you’ll want to return again and again)
Tallinn (really quite small (intimate) and last time I went – 6 years or so – the lack of tourists was noticeable – lots of Fins come over on the ferry for the weekends, Friday night is the big night – got to meet lots of locals who we tagged along with and took us to the best places)
Krakow (loved it here even though I did get sprayed with CS gas in a club within 2 hours of arriving – did the usual trips Aschwitz, Salt mines but the best was a ‘communism tour’ where a few local youths had got together, bought a couple of Trabants and took you well and truly off the tourist trail, simply amazing day drinking vodka with them all day)
Budapest (went about 10 years ago and have been itching to get back ever since, again fairly quiet, well it was back then, hire bikes and go to Margaret Island via the tower blocks along the Danube, Margaret Island was one weird place, imagine somewhere deserted after a nuclear attack)
Anyone been to Gothenburg, Bucharest, Munich? what’s there, would it suit a few days over New Year with celebrations etc.
