OP - you can save money with
DVC. But the number you oriignally quoted is high for your savings.
Here is a little something I posted about a year ago when someone claimed that you won't/can't/don't save money buying DVC and going from a regular room to a 1BR...
Time for some real world math experience for illustration to the naysayers...
Prior to buying DVC we stayed at GF, always at GF, every year for about 10 years. We used to get a room discount years ago, but were striking out most recent years. So here we go...
GF garden view rack rate - $435
2010 cost for 7 nights, with tax - $3,630
But let's be a little conservative and assume we might get a 40% discount every other year. So we restate the GF rate to 80% of current rack rate.
GF garden view rack rate - $348
2010 cost for 7 nights, with tax - $2,903
As regular room rates go up every year, let's use a 4% average inflation increase (we'll use this same rate for maintenance fees on the DVC side).
Here are the cumulative GF 7 night room costs:
5 years - $15,726
10 years - $34,859
20 years - $86,459
30 years - $162,840
40 years - $275,903 (though I don't know if I'll still be alive in 40 years)
Now for the DVC numbers...
A 7 night stay at BLT in a 1BR LV in Choice season is 240 pts, 274 for Dream season. So let's stay conservative and use a 260 pt need for our week's stay as we cross seasons occasionally.
260 point cost in 2010 at the current $110/pt - $28,600
Let's assume maintenance fees are $4/pt and will grow at that same 4% inflationary factor we used for the GF room. 2010 MF - $1,040
Since we paid cash for the points, we have lost capital use of that money. I'm not getting anything near this now, but let's assume the old standard 8% cost of capital factor on the money I don't have use of because I spent it all on pts. So in 2010 it's going to cost me another $2,139 to not be making money off that money I used to buy the points.
So here are the cumulative 7 night stay costs for BLT:
5 years - $43,962
10 years - $55,835
20 years - $74,714
30 years - $102,073
40 years - $142,571
Breakeven - year 17
Under this conservative model I break even at year 17 and save $133K over the 40 years of vacation. I say it's conservative because I'm not staying at less point resorts, taking a standard view every so often, and I didn't add back in the cost of capital on the money I'm actually saving starting in the latter years.
Now, my real numbers were a little better since we bought at $97/pt, will occasionally stay at lesser point resort and lower point room category, and I'll be lucky to have a cost of capital of 5%. I think I'll break even on a 1BR in 10-12 years. What if we stop going to Disney in 10 years, around the time we break even? I think it would be fair/conservative to assume we could probably sell for at least half of our initial buy-in cost and be up $14K. I'm not planning on doing this or recommend doing it as an investment, but that's just how the numbers play out for us.
My real break point is around 10 years - so I think I'm good. But even when all the stars are misaligned like in my example case, I showed that you can still get a decent deal changing over to a 1BR.
Also, the assertion that anyone can get a discount is a big leap. No discounts available at the GF for the weekend we want in Dec this year - I checked.
