Hey, wow, I just had a bit of a lightbulb moment in the shower, always seems I think more creatively and clearly in the shower, weird.
Anyway, imagine this scenario...
You are the wife of one of the most powerful men on the planet, and you have much wealth and manpower at you disposal. You, and you family, are about to be shut-into an underground bunker system, for, say 2 years or more, who knows? You and you children will not see the outside world, mostly because there will be massive destruction or unsafe living conditions above ground. Also, all the beautiful, historic, enjoyable places you'd like to see in the world may also be ruined forever from whatever you'll be hiding in the bunker from.
Seems like a good time to take some around-the-world family vacation time, eh? Get a taste of it before it's gone.
Too bad we can't all do that.
