Italy: I recommend it, it was beautiful and has a very kind culture.
Germany: I had fun there, but I recommend going with other people, if you're an American you'll have a blast getting drunk with some random group of German guys!
France: I don't like France.
Switzerland: Oh my god, so beautiful and friendly, will go again!
Japan: This was a fun trip, lots of culture!
Austria: Don't really remember it, we were not there very long.
Oman: Eh, some beauty but it's a commitment.
Jordan: The dead sea is a must!
Lichtenstein: More of a tourist trap, it's a must because it's small
Vatican City: Was a must.
