We're going to WDW in 10 months and my sister is going with us. We told her to purchase disney dollars throughout the next 10 months to help spread out the cost. She wants to use them to pay for hotel, food, etc. Well, when we told her this, we didn't realize that the largest increment is a $10. Has anyone ever done this with a large bill and paid disney dollars? I'm almost embarassed that I suggested it to her now.
