I agree with most of the other posters, but wanted to make a couple of comments.
First of all (and this is a very minor point), ANY timeshare (or any other kind of asset) can be passed on to your children. There is nothing unique about
DVC in this regard; just a sales point for any asset with a long life.
Second -- I think the first decision that
should be made is often just assumed by prospective timeshare buyers. That is the question of
"Should I get involved with ANY timeshare in the first place?"
People considering timeshares (myself included the first time around) often don't really look at the enormous ranges of options. Timesharing is just one option among hundreds of ways to pay for vacation lodging -- it's great for some people, and a big mistake for many others.
I think folks need to take a clear-eyed look at the concept of signing up for a 30-year to never-ending
financial obligation before they start trying to decide whether they like one resort's bedspreads better than another.
Third -- I think it's important to evaluate timeshare systems based almost exclusively on the value offered by the
resorts in that system. Any of the other options (exchanges, cruises, etc) rarely offer similar value to the systems internal resorts. And those options are also subject to radical change at any time with little or no notice.
When I was looking at other options, the best single piece of advice I received (from Dean, Brian, Culli, and others) was to really take a close look at the network of available resorts within the systems I was considering -- and do that assessment in terms of where
we would like to go on vacation, rather than someone's glowing report on a place we would never want to visit.
The value of available resorts is not the same for everyone. OP is considering Welk, which I believe only has 4 resorts...three of which (Cabo, Branson, and Palm Springs) I don't especially want to visit. Other posters have mentioned Worldmark. That's a great system, part of the Wyndham family and primarily offering resorts in the western US. Great for people who live out west; not for us...although I'm sure we'll try to use our Wyndham points at a Worldmark or two sometime.
We own Wyndham, which has about 80 resorts. Wyndham is strongest in the eastern US, but they have a strong presence in Hawaii (11 resorts there) and they're growing in the west. For us, Wyndham was a good pick, but it would probably not be the right choice for many other families. One of the other systems mentioned above by Dean might work better for others.
DVC is
not an exception to the "look at the internal system" rule. You have to consider the use of DVC points within the DVC system, as well. That's where the value is -- nowhere else.
For us, the only place we would use DVC points today would be
at WDW. If it's really important for you to stay onsite at WDW, in larger than hotel room accommodations, DVC is the only game in town.
We have used DVC in the past at HHI and Vero, but now with Wyndham we have much more attractive options for those types of vacations.
We also have better options in California (Wyndhams at San Diego, Oceanside, Ventura, and Anaheim + San Francisco and Lake Tahoe in the north, and we have limited access to some Worldmark resorts in CA) and 11 resorts on three islands in Hawaii. So outside WDW, we would use Wyndham, not DVC.
