12.5% If I remember correctly.
I have 3 years left on my mortgage, I did uhm and ah about wheter it was a good move, but in the end I was really glad I did. On a recent cruise I went to a DVC meeting and was surprised that points are now running $185 per point, wowzers, thats not far off double what I paid seven years ago. Bottom line is my DVC is getting more and more valuable as each year passes, whilst room rates go up and car park and other fees are introduced my points per night will always be the same. Granted the annual dues will go up but i'll still be quids in.
If you use rack rates, then Ive already used more then my mortgage cost and stayed in resorts I would never have paid $$$s for and I have over 40 years left to run on. Granted it's not for everyone but for me, and my family it has been a great investment.
The newer resorts give me more choice of places to stay too, adding more value, so for me, maybe selfishly, I say keep em coming.
