I think it's time we start seriously considering dvc for our growing family ( 5 kids). I've realized two things while perusing the threads here.
1 - there is A LOT I should know before diving in.
2 - I don't know most of it.
This is the BEST starting point I've seen expressed here in years!
I wish more prospective buyers began the process with this mindset.
Others have given you some great starting points for your research. The thing I would emphasize is that
DVC is a timeshare, and it involves a 30-50 year financial commitment to annual maintenance fees depending on which resort you purchase.
With any timeshare, it is critical to understand exactly what you can use it for, and how that fits your family's anticipated future vacation needs.
Any timeshare works best within its own internal system (in the case of DVC, using points at DVC resorts only). Any outside use of the timeshare (exchanging, etc) is likely to return less value -- often
greatly reduced value -- and will usually be unreliable and unpredictable at best. External uses are usually not guaranteed, and can and do change from time to time.
IMHO, for most families, DVC works best for stays at the WDW DVC resorts only. In the other locations (Vero, HHI, Anaheim, and Hawaii), I think there are less-expensive and better options available. Others will strenuously disagree with me on this, but that's what discussion boards are all about.
I think it is also good to remember that DVC is only
one of a group of quality timeshare systems -- certainly not the only one, and not necessarily the best timeshare for everyone's needs. Hilton, Marriott, Starwood, Wyndham, Bluegreen, and others are very good systems and most of those can be purchased for a fraction of the cost of DVC in the resale market.
