has to be in this order for me for weekend breaks, having travelled extensively and not including any long haul ive been to

prague
vienna
bruges
saltzburg
budapest
dublin
amsterdam
paris
venice
sofia
shanklin

As we are restricted to long weekends away due to my wifes health Venice - for the shear ease of getting around - no traffic to worry about
Paris - been every year since 1992 - perfick
Brussels/Bruges - first time this year will go back
Prague - again first time this year but def return on the books asap
NYC - what can I say it just buzzes
Amsterdam - ok
Rome - superb(going back in October)
Barcelona - very good but not a need to return type of City for me
Athens - we just love the attitude, food, sun and history

The basic truth is that every City has its plus and negative points. But anywhere can be fantastic if you just relax, enjoy and appreciate
