After hours of worrying, countless webpages and half a dozen 'the final door is now closed', I really don't know what I was worrying about at all. At all. Everything was fine, there and back. The only problem would of been only getting 30 minutes of sleep on the whole trip back, but seven movies later and at least I feel more educated.
So since the plane trip was a success, the trip had to be one to, and well, it was. London and Paris and Rome oh my. Now, I believe, a bed is calling.
