We are thinking of going to New Zealand for Christmas with my brother, taking 3 DSs, who will then be 9, 6 and 4. About to book and not sure if we should go straight through for 24 hours, or break on the way (LA, Singapore, Dubai, even?). Would love any advice on whether a break makes things better or worse, or on where might be a good place to stop. We can be away for about 3 weeks, so time important but more important to arrive alive....
