Vatican City

Okay, obviously if you're going here, you're here to see the Vatican and everything. Get there early. This is one thing that you should just wake up early and plan on doing, especially if you're there during the summer. If you're there during the winter months, it's not going to be as bad, but if you're there during the summer especially, just plan on waking up like seven probably and heading out maybe even earlier. I don't know. I know that they don't open till later, but there's already going to be a really long line and if you want to pay extra, you can skip the line. Be aware that that is an option, but be prepared to wait in a long line.
