My wife and I are a surgeon and a corporate lawyer. We take some baller vacations. I'd still call $1500 an expensive vaction. I wouldn't call it an expensive vacation abroad because that's really on the low end of things if you're two Americans going abroad on vacation (you're looking at, in a dream of dreams, $1,000 just on the cheapest tickets you can find to a country you picked just because it's the cheapest destination right now, and that's without including food, housing, and things to do—certainly for two people to fly across an ocean for vacation, they'd really have to penny pinch to come in under $1500 total). But it's certainly an expensive vacation if you're just talking about vacations in general.
