We're lucky enough to have enjoyed a number of city breaks since children were old enough to be left at home. Looking for ideas for more unusual places to visit. As it's just for a weekend, don't want particularly long flights - max 3 hours pref less.
We've been to: Paris; Berlin; Munich; Frankfurt; Vienna; Innsbruck; Marrakesh; Prague; Budapest; Lisbon; Dubrovnik; Split
On the list already are: Bruges; Amsterdam; Milan; Seville; Bilbao; Madrid; Carcassonne; Krakow
Where have you visited that you'd strongly recommend as a werkend destination? Apologies in advance if I say we've already been somewhere you suggest, I've not listed the places we've visited on summer holidays
