Milan, Rotterdam or Vienna

Bedders

Looking at Spring marathon's for next year, ideally I'm after one that's in the Easter Holidays (fits easier with family etc), and on the continent. Did Paris earlier this year, Barcelona the year before and Edinburgh in 2011.

The three I'm looking at are Milan (April 6th), Vienna and Rotterdam (both April 13th). Has anyone ran any of these? Any recommendations or views to share?

I'm a bit of a sucker for a BIG city marathon (Barcelona was superb, Paris even better) but it doesn't necessarily have to be a huge field. And somewhere with a bit of life going on as well for a few days jolly after the race....!
