Sure, why would Americans want to visit some of their longest standing allied nations and the Mediterranean? Where English is either the native language or spoken by the majority of people in high tourism areas? Where some portion of their families are most likely from?

That being said, no trip to Europe would be complete for me without going to at least one Scandinavian country. I met the woman who is now my wife a few months before I was meant to take a trip across Europe and ended up canceling my plans to take a shorter domestic trip with her instead. But I was going to fly in to England, take a train across France to Italy, then across Switzerland and Germany to the Netherlands before flying back to the States. No regrets staying with my wife instead taking the trip, but I do wish we’d have been able to go later. So far, though, I’ve never been. And since we have a 2 year old and are trying for another, we’re still likely years from such travel.
