I have a relative who is a vacation dictator. In her view, if your life choices (career choices, vacation choices, family choices) are different than hers, you are automatically wrong.
She would *never* go to Vegas, so she is derisive about the loose morals of anyone who would choose to go there.
She only cruises with Disney. Anyone who can't afford a Disney cruise should simply not take a cruise at all, because all other cruises are hotbeds of filthy sex acts, 24/7 drunkenness, and immoral gambling.
She likes active vacations, where you are on the go 12 hours a day in order to do as much as possible, so she cannot compute that some people want to go on vacation to relax, sit by the pool, have a margarita and bask in the sunshine. "If all you're going to do is lay around, you might as well stay home."
She is very judgmental toward anyone who would "waste" their money to go to a tropical destination--if all you're going to do is lay on a beach, go to a local lake instead. (Never mind that there is absolutely no comparison between a muddy midwest lake and the beaches of, say, Hawaii.)
People should vacation in places rich with history, but only the right kind of history. Munich, Barcelona, Prague, etc. are great. Paris is terrible and filthy and perverted, and anyone who would choose to vacation there is both wasteful and questionable. London is "pointless", so anyone who goes there is wasting their money.
Ancient sites are worth seeing. Modern sites are garish and filthy and worthless.
Vacations require a rigid itinerary. Anyone who travels without a written itinerary (including wake times, bedtimes, meal plans, and precise times for each activity) is foolish and wasting their money.
ETA: And if you don't pinch every penny until it cries, you are wasteful and foolish. No one needs restaurants or decent hotels. Eat plain bread and fruit two meals a day, and cook the third meal in the crappy kitchenette of your interstate motel. After all, food is food, and you should only use your hotel to sleep (and thus you have no right to care about anything else in the hotel).
