A destination very far away

I married my husband out of love, not because of the country he comes from, as it is possibly the most unpractical country to travel to from Europe: New Zealand.
New Zealand certainly has a lot of advantages, namely it is 30 degrees there at the moment (not 2 degrees as in Paris), and the New Zealanders were the original inventor of the Ugg boot!  They also host important cultural events like the international gum boot throwing competition and the world famous golden shears championship!
I am actually really looking forward to being in New Zealand. It is the getting there with the 2-year-old toddler that fills me with dread. How do you keep a 2-year-old happy and quiet for a 24-hour flight there and back??
