We had ddp and reserved with cc, not charged, as previous post stated. We paid OOP for adults, but used double ts for children (ages 9 and under). Since children are only $10 a double ts has a net value of $20. At the time we went, Cinderella was around $23-$25, so by using ddp, we came out ahead by $5 and the two cs and snacks with those ts's are then essentially free.
At our other ts's we paid oop for the children because a child's meal is only about $6-8...
