Recommend me a travel insurance policy?

[Mario149]

My other half and I are going on holiday to India shortly and leaving the kids at home with my sis. Looking for recommendations on a travel insurance policy to take out, specifically ref having to curtail our holiday if we need to get back to the kids for an emergency or similar. Added to this is it's a bit of a once every blue moon "blowout" trip: we're flying first class, doing fancy hotels etc., so if we do have to curtail, I'd like to be able to recover the not insignificant costs.

Normally we just do InsureandGo (they do have curtailment on their policy but can't seem to find any detail on it in their policy handbook), but wondering if anyone else can make a recommendation?
