In reply to Dave Sarkar:
why limit yourself to Europe/USA ?
South America is cool, great with kids as well, they can come and then you depart for climbing before catching up with them for family fun
always wanted to go to Killi to see the snow - guess not much time for that - if your kids are old enough take them up it as well, if not they go on safari while you take 6 days out before catching them up
egypt and morocco have good areas, for cragging and multi pitch stuff, or even walking peaks that would also do for family holidays
depending on age of your kids Russia is an AWESOME place to go, you can take soem time out to blast up a hill or two for a few days within the bog standard 14 day family holiday
India with kids is VERY do-able as well
