We love to do a city break in Feb and I was wondering if anyone has done Krakow in winter? It will be me and DH and our two boys, 15 and 11. They like cities, eating out, guided tours with engaging guides, a bit of history, did I mention food? They do like to eat 
And a nice hotel. Older one appreciates a good gym, younger one a nice pool, so any recommendations of well-located, family-friendly hotels would be great.
