Indeed.
DH sometimes tells me about conversations he has with coworkers who've asked where we're going on vacation this year. "The usual, Disney World," has become his response.
Those inquiries turned into incredulity when he said we'd bought into DVC. Upon his explaining how much money a buy-in often requires, coworkers were almost universally, "It costs HOW MUCH?" or "Can't you just get a hotel?" or "Wow! I bought my kid a good used car for less than that."
The only one who really gets it is the coworker who goes to WDW annually like us and bought into RIV last year, graciously naming us as having recommended DVC to her.
Virtually everyone else we know except DH's brother and family don't get it at all. "Jim" explained to their dad that DVC isn't any old timeshare. It holds value. If they didn't have kids in college, they'd buy in, too.
It's easy to forget how little most people get us DVCers' dedication to Disney trips. Honestly, it's not normal adult behavior unless you have kids. Only then do non-Disney goers kind of get it.
