Sure, if you bought 20 years ago, you are looking good.
If you bought CCV, you are probably losing money, maybe a whole lot of money, if you need to sell now.
Resale can help this math and make it less commitment, but I would definitely not buy DVC expecting to make money. This is a prepaid, expensive hotel room in the form of real estate. It costs money to sell and buy, and it is a big commitment. It will save you money against deluxe properties, and fancy bookings like 2BRs, but not against bookings like AoA or AirBnb.
