About 6 months ago, Disney ran a similar promotion and offered $25 Bonus Rewards. I signed up for a Disney Visa card then. Here's what happened:
1. Received my Disney Visa card in the mail.
2. Made a minimum purchase - $10 at the gas station
3. When my statement came, I had 25 points on my statement.
4. Called Disney and asked for a "Disney Rewards card".
5. They transfered the points onto a separate Rewards card, which I then used at the Disney resort.
I think that this promotion will be the same way. Hope this helps!
