Well I purchased DVC with my senior dad (shared expense since we both love it). He and my mom had been on this kick to buy enough Marriott weeks so they could leave one to each of their 4 kids. But two of my siblings purchased their own timeshare weeks so don't really need them (or can use them). I started managing the vacation portfolio for them from the getfo (I had been their
travel agent before anyway) and try to ensure that everyone can have use of it. With Marriott that means some shared timeshare stays and several hotel trips with the reward points.
Now Disney is special. It is the one timeshare I know I can travel to solo with minimal hassle. Marriott requires me to bring my specialized van on a long road trip (I can't just rent a car like everyone else). So when we purchased it, it was solely so I and my dad could use it for as long as each of us is physically able. I also made a point of setting it up so my sibs and therefore the family could inherit it if we both croak before the contract expires. (I'm big with estate planning and avoiding the hassle of probate.)
Now we're envisioning the Marriott weeks as part of a vacation portfolio trust to be used as best as possible for the family. At least one week is designated for each sibling's family. Then there are a bunch of young grandkids around so possibly they will get some very nice vacations with their friends out of it. (Spring break in Ft. Lauderdale one college year, perhaps, a honeymoon in Thailand.)
DVC is one I'll use most. But I love bringing folks down with me so I expect everyone in my family will get their turn at invitations. While there is a lot of interest among some of my family for
Disney vacations it is nowhere near as strong as my dad's and my interest. But I figure we have maybe a good 5-10 years of solo travel before health declines take their toll on my dad's travel. By then the grandkids will reach their college years and perhaps we'll find a few more young and able helpers to give my dad another 10 years. Ideally I'd like him to spend his last vacation at Disney, just like my mom. I wouldn't mind doing that myself either.
Hate to be morbid, but realism is never far away once you lose a parent. (I just had a website client and friend this week who passed away. She was 6 months younger than my dad. And he sees his cardiologist tomorrow for the stress test report. So this is something I think about and worry over daily.)
Rather than worry about if your children would like to inherit DVC, I'd think more about how you'll be able to continue travelling when age and disability hit. Since Grandpa Mohawk and I cover the "age" and "disability" obstacles already, we could probably give you a few pointers. One thing I know for certain. Disney is the easiest vacation to take for those a little more challenged by life.
