Im a DVC member and its worked out fine for me.
Tip from me ,even if you dont want to buy go to a booth and get an appointment so at least you have a chance to look in some of the rooms and I got a perk from them for doing so.They dont push you to buy and it was acctually quite entertaining.
$25,000 is a high quote, I paid much less than that! I think $12,000 is the starting price these days.
Most people who go to Disney regularly anyway, it makes sense to do DVC. The only exception might be people who know a castmember who hooks them up with discounted rooms all the time.
I don't mind the booths in the parks, the people are always nice and tell me WELCOME HOME when I tell them I am a DVC member. And the tour is actually pretty fun I did it a couple of times over about a six year span before I ended up buying. And I really wish I could turn back the clock and buy it that first time!! I would have spent so much less!! It's not a high-pressure thing though I think like 1 out of 20 people buy or something so they are definitely not expecting you to pull out a credit card.
