Just wanted to update what happened when I took my rewards card to the
Disney store to buy gift cards - I purchased a $500 disney gift card with no problem. I was very doubtful when the sales girl told me I could use my rewards card - I made her call the store manager to make sure. When she rang up the gift card, she had no problems using my rewards card as payment. Hopefully this will help others who need to use up rewards dollars before they expire - it was a very simple, easy process to convert them into a gift card!
