I'm one of those people who keep a spreadsheet carefully tracking all my expenses and value related to my DVC, carefully calculating "break even" -- and using real world values for the stays (ie, if discounts were available, the discounted rate). I recognize that I gave up some long term savings that I likely would have kept in investments and not drawn down for
Disney vacations, particularly because I also recognize that we both would have done
fewer Disney trips without owning DVC and
we certainly wouldn't stay in the accommodations we have.
That said... I am also someone who puts a
high value on experiences, and one thing my DVC has allowed me to do is create experiences, for my family and loved ones, that I wouldn't have been able to do without owning DVC.
Last year, I took my family and my inlaws and a number of our friends to Disney, and we used DVC to cover the rooms. As much as I'd love to say I'd have done this anyway, the reality is I wouldn't have done it if I had to pay out of pocket - I would never have spent that much money on a single trip. But it wasn't a single trip. It was
just one of many trips, and I have future points to spoil family and friends (and myself, of course) with in the future.
For me, it is the value of all the past trips, and all the future trips, and those times spent together as a family, enjoying time together, that is the true value of owning DVC... and that is difficult to quantify, because you can't put a real dollar value on that.
Maybe I'll get to retirement age, and wished I had spent less on DVC and more on future savings, but I'll also get to retirement age and have decades of memories of what I did with those DVC points.
Not to mention I'd never pay Disney prices for a 2-bedroom villa or a Grand Villa, but owning DVC has allowed me to experience those, and they add tremendously to our enjoyment and comfort during our vacations.
