ok, we are in the ridiculously luxurious position of being able to go pretty much anywhere for 2 - 4 weeks in December/Jan!! I know, can't believe it myself...
but we have 2 DCs who will be 1 and nearly 4, so not that keen on longhaul, and definitely could do without jetlag.
so the question is where would you recommend that is adventurous but child-friendly, good enough weather to be outside but not too hot and stuff to do with kids. ideally there would be other kids around too so that they can entertain themselves and dh and I can reeeelax .
