No, as a matter of fact, we stay 12 nights each year in an OKW GV. The weekend points are rough, but you can minimize them. We have 430 points and pay near $1600 in dues, really, sooner or later, you will only be paying dues. I figure I get a 2500 sq ft three bedroom villa for $150 per night.
Many people are cheap, they can't brong themselves to stay in the same room on the weekend that cost them near half the points the eveining before. If you look at your whole stay and average the points per night, its still a great deal.
The number and length of stays you are talking about do merit the consideration of an offsite house, there are many cool aspects of that, Florida residents passes, appreciation, very truly a 'home away from home'....it would probably cost less than DVC...but so would rooms at the All Stars.
What size room do you want? You may be first thinking a studio is what you are used to, you are a family of five, a two bedroom is needed for both following the rules and real comfort, we are only a family of three, we get the GV and bring guests, different guests each year. While a two bedroom would allow the kids to bring a friend, maybe even two, a GV or an offsite house would allow you to bring another couple and have all the dopey kids share the third bedroom.
Cheaper and financially sound, the off site house.
Truly carefree and extravagant vacations, 2,000 OKW points, $140,000 up front and some $8,000 in annual dues. If that's doable, the $8,000 in dues annually will be buying you WAY, WAY more than you caould get onsite through CRO.
Really, the money you spend on the house is in an appreciating asset, the money upfront into DVC will still be majorly recoverable for ten years, partially recoverable for many more years and worthless near the end.
Same thing with my Lincoln Navigator, I could have gotten a Kea station wagon, it would get me to and fro and would have cost less, I didn't.
Financially, the house is wiser, but 2,000 points is more fun.
