Cinderella's Royal Character Breakfast requires a credit card at the time the priority seating is booked. WDW Dining will require that the name the PS is made under not be changed. At the time the PS is booked, a deposit of $10.00 per adult and $5.00 per child will be charged to the credit card. Once the PS is booked no names may be transferred to the reservation. You may cancel 24 hours before your PS without losing your deposit.
It is important to remember a couple of important items here. Your credit card will be charged immediately once the PS is booked. In order to cancel your PS, you must call WDW Dining at which time your credit cared will be credited. Lastly, and maybe more importantly, names cannot be changed or added to the PS after it is booked.
