DVC is not the cheapest way to vacation to WDW, value or offsite is.
DVC is not the more luxurious way to vacation at WDW, a suite or hotels like the Four seasons are.
DVC doesn't offer the most space, a villa with private pool on Airbnb does.
DVC is not the most flexible accommodation, paying cash with generous cancellation policy is.
DVC is not the most convenient way, just the UY explanation is 3 pages long.
The only reason to buy DVC is if it saves money over comparable accommodations. Anything else is moot. I don't buy into other factors like "owning the magic" or "be part of the club".
DVC must either save you enough compared to accommodations you'd book. Or allows you to book better accommodations for a price tag you're happy with.
I've bought because of the latter. I have divided the buy in cost by 10 years (an horizon I was comfortable with), added MF and found out I could stay at deluxe resorts for just a bit more than I would have paid otherwise in a value or offsite.
I could afford to pay cash with savings I didn't
need for anything else. I could afford the MF. 11 years later and I'm still very happy with my decision.
I haven't saved a penny, actually I've given to Disney and British Airways an always increasing amount of money, year after year. But I've stayed onsite in wonderfully themed resorts that I would never book had I to pay cash.
So, yes, it's a toy and I can afford it, but it's also convenient according to my calculations.
