JMC: the current promotion is a "free vacation" OR $10 per point rebate on your purchase.
The free vacation must be used at any DVC resort EXCEPT SSR and must be completed by September 30, 2005. If you purchase 150 points, you recieve 150 points, if you purchase 200 points, you get 200 points.
The Magical Beginnings discount is $10 per point rebate so if you purchase 150 points, Disney will credit your downpayment with $1500.
You can't combine the discount and the free vacation. Hope this makes sense Thanks!
