I have to say that I'm not sure you should cancel.
Saratoga Springs at $99 a point with 100 points- with FULL VALUE points (not bought on the secondary market) is a good deal, and a great start for your family. You travel to WDW every year - or every other year, just think about what you are going to spend over the next 8 years, going every other year.
You are essentially spending the same thing, just all at once, and financing.
You are talking about $9,900 - half of which you will finance - so $4,950 out of pocket, and the same financed.
That's $618.75 a year over the next 8 years - that's $51.56 a month - $1.69 a day.
I just used 8 years as a random number - no real reason.
Just remember that ownership will be until 2054 - so that's a LONG time.
If you are going to be spending $1,000+ every other year or so, you will get the value out of your ownership.

DVC has totally changed the way we vacation - it's not IF we come back to Disney - it's WHEN. We will go every year from now until - ? Who knows when. Even if there are years that we trade out, or just go to Florida to soak up the sun, and don't even go to a park - we don't have to worry about where we will stay. We love the rooms, we love the ease of use, and most of all - we LOVE that we won't have to worry about inflation and price increases.
As you can see in my signature - we own at 4 resorts, and are ALWAYS planning out next vacation! Either to relax - or tour the parks - or take a cruise!
