My aunt, who is super wealthy, has just offered to pay my wife's way on a pretty pricey girls' week trip with all the ladies in my extended family. It's a trip that we wouldn't probably be able to justify otherwise, on two teachers' salaries with two young kids, but it's not an issue for literally anyone else in my family because everyone but us is stupid rich. They're not the type to flaunt their wealth and it's a sincere and sweet gesture, but taking someone else's money for something like this makes me feel uncomfortable. Any advice, all you old money types on the boards?
