You're going to find most people that hang out in these boards love Disney and
DVC and are going to say that it's the greatest thing since Velcro. I'm one of them, and from what you describe, I think that you are probably a good match.
In my opinion, the ideal family for DVC would start with a love for visiting Disneyworld (and
Disneyland). They like to stay on property and enjoy larger rooms with no problem committing to vacations to Disney at least every 2-3 years. The more you want to visit, the better fit, but also the higher number of points needed. Money in the bank to purchase the initial points is certainly the best way to go. Paying the annual maint. fees is expensive without having a loan payment to go along with it as well. Occasionally, the ideal family may want to use their points for
DCL or other RCI trade outs, but the primary use is to stay at DVC properties. Their travel party size may vary at times requiring only a Studio, while other times they need the added space of a 2-bedroom or Grand Villa.
A bad match for DVC in my eyes would be a family that has very little money saved up to purchase the initial contract and needs to finance the bulk of it. Their plans are to use the Cruise Line options and RCI tradeouts for the majority of their points and plan to rent out other points and they have no desire to commit to regular
Disney vacations. When they do like to visit, they prefer the onsite value properties, or even off Disney property.
Only you can decide which is right for your family though. If you do think that you're a match, make sure that you research Direct vs. Resale. You can save a ton of money going resale, but will add some limitations to your options. Resale does allow you to purchase any DVC property as your home. Direct will try and drive you towards the currently offered properties, but you can get on a wait list to get the right resort for you. Regardless, you won't go wrong if you purchase your home resort to be a place that you like to stay at. Good Luck!
