I imagine you could e-mail them to Disney customer service.. I don't have the address, but I am sure someone here does.
Next time you have good service you might want to stop by guest relations.. we did this on our last trip when two CMs were so very helpful to us. We had to fill out a little form with the CMs name and our name and we were informed that it went into their permanent record. The more good cards like that they had, the more likely they were for promotions or raises.
