This group tends to be very happy DVC members. But to provide some perspective to your question, here are some reasons why DVC might not fit:
1. can not comfortably afford the initial purchase
2. do not want to commit to the annual dues
3. unsure if they want an annual or every other year Disney vacation
4. can not plan vacations well in advance
And here are some of the reasons why we like this program so much:
1. flexibility -- when you go, how long you stay, the size villa you use and the resort you stay at
2. banking/borrowing -- ability to bank points from this year to use next year and borrow points from next year to use now
3. value -- over time you can stay in one bedroom villas for the equivalent cost of a moderate resort hotel room
4. resale market -- DVC holds value well and there exists a very active resale market to add to or dispose of your contracts
5. deeded right-to-use ownership -- can be passed on to heirs
6. Disney brand -- backing and management by the Walt Disney Company
There are specific rules governing the program and these features. Overall this is a well run program for anyone who regularly enjoys Disney brand vacations.
Good luck
