I don't know about the limit, but I've purchased Disney Dollars a couple of times with my CC. I believe that I got $30 in singles each time. I buy them before Easter, then on Easter morning, Tigger visits our house, and bounces around attaching Disney Dollars to trees, bushes, grass, and anything else he can reach. He attaches them with tiny plastic clothes pins that he buys at the Dollar Store for real cheap. He also leaves a package of peanut butter cups for each child, and perhaps a couple of little Disney things here and there (this year DS5 got three "T" shirts, and a sweat shirt). The kids then have a GREAT time searching out the Disney Dollars, we don't waste a ton of hard boiled eggs (which no one really eats) and the kids don't rot their teeth out of their heads with 20 lbs of candy.
