You are all missing the posters point I think. You need a vacation, go! But be reasonable. The question is more should any Jew spoil themselves in the lap of luxuiry, live ostentatously, etc. Many gedolei mussar would say not. and that is without considering the fact that many can’t put bread on the table. The phrase, “if you’ve got it, flaunt it” as regards to money, is not a Torah concept. There are some gevirim who live comfortably but far below what they can afford, because thay believe in living simply. (But they are not stingy when it comes to tzeddaka) Admittedly this is a very high madreiga and attainable by very few.
was this the point you were trying to make noitallmr?
Another consideration would be the inevitable stress and raising of the bar of the rest of the community. This is an unavoidable fact, as was widely discussed in the chassunah takanos, but which can be applied to vacations as well.
Besides, what are you teaching your kids?
I heard a cute but sad story from a New York speaker (dont remember his name, but well known speaker) That he overheard two teenagers talking about what they did for vacation. the first said he went to the Bahamas, or some other exotic place. The second said, “yeah, we did that a couple of years ago. It’s so boring.” so what did you do?, asks the first. The second answered, “nothing. we just went to Florida.”
JUST.
so there, noitall, three suggestions why one should take pause before taking an expensive vacation.
