The best value city breaks Andrew Brown of Post Office Travel Money said: "Rising prices in most of the cities we surveyed, combined with the falling value of sterling, make it more important than ever to check prices for key items like meals, drinks and sightseeing before booking as these are costs that most city break tourists cannot avoid." Post office exchange rate comparisons for City Costs Barometer destinations, 18 March 2013 compared with 18 March 2012. The most expensive cities in Europe were Swedish capital Stockholm and Danish capital Copenhagen, where the 12 city break costs included in the survey totalled £420.36 and £440.45 respectively. The survey found prices had risen year-on-year in 22 of the 25 cities surveyed, with the biggest increases in Vienna (26.3pc), Boston (28.4pc), Riga (30.7pc) and Stockholm (33.0pc). The three exceptions were Berlin, where prices were down 1.5pc, Prague, where they have fallen by 6.8pc and Lisbon, where lower sightseeing prices helped pushed costs down 19.1pc, making it the cheapest eurozone city. Mr Brown said: "There are big price variations across Europe - not just in the eurozone. This means UK holidaymakers can make their pounds stretch further by choosing a cheaper capital like Lisbon or Budapest. Dubrovnik in Croatia emerged as the top 'emerging' city destination that tourists would like to visit, followed by Moscow and Krakow. If money was not a consideration, New York, Sydney and Rio were the top choices.
