Top European City Weekend Breaks

I'm very keen on seeing a lot more of Europe, so I've drawn up a list of top European city breaks where I'd like to visit over the next few years. Most of these are places I think would be great to see and within a short flight from the UK, but perhaps more suitable for a long weekend break rather than a week holiday:

Belguim:
Brussels
Bruges

Britain:
Edinburgh
Bath
Belfast
Lake District

Italy:
Rome
Milan

Portugal:
Lisbon

Germany:
Munich

Scandinavia:
Copenhagen
Oslo

Spain:
Madrid
Valencia
Seville

Switzerland:
Zagreb

Greece:
Rhodes
Athens

Czech Rep:
Prague

France:
Lille

Austria:
Vienna

Croatia:
Zagreb

Morocco:
Marrakesh

There's other places I'd like to visit too but this would probably make quite a good start! I've left off the places I've already visited such as Venice, Barcelona, Paris, Dublin and London but all of these are great places so would definitely plan on going back in the future.

As for other holidays, I have no plans at the moment but would definitely like to visit the following places for a break in the sun:

New Zealand
Fiji
Greek Islands (Skiathos, Mykonos)
Algarve
Caribbean (Cancun, Barbados, Bahamas)
Sharm el Shiek
Cape Town
Mauritius
Dubai
Hawaii
French Riviera (Monte Carlo, Nice)
Malaga

I also plan on seeing a lot more of the states, having been to Florida and LA so far I'd like to visit the following places too:

Seattle
New York
Las Vegas
Chicago

Plus there's other places in Australia I didn't get to see last time, mainly Perth but also Adelaide and possibly Darwin - and definitely going back to the Whitsunday Islands!

I have a travel map of where I've visited (from Tripadvisor) on my Facebook profile, so far I've been to 95 cities in 10 countries - would be nice to get this upto 100 pretty soon!
