"But before you start to envy me, I will be stuck in a car for 10+ hours with three kiddos for two of those days! :P"

Good thought, but unfortunately, I have a minivan...
But luckily they are super spoiled by grandparents and have a couple of iPads and I just bought headphones for them! Downloading hours and hours worth of movies! :P
