The hard part of traveling overseas isn't even the voyage itself, it's what has happened to your brain by the time you've reached your destination!
I do have to say that I'm humbled by this family's journey, and don't expect mine to be nearly as challenging.
Of course the packing and the leaving and the sitting and the lugging bags are a hassle. But when you arrive in a place 8 time zones away, well, it's a bit hard to focus. So the anticipation is like preparing for an operation that may leave you with temporary memory loss. And you feel like tattooing your name and phone number on your hand, just in case.
