Did you still pay for the cake?? I can't believe the manager was aware that you were disappointed with the cake and it was not what your order, but you still had to pay for the cake!
It is completely unacceptable for these cakes to come out less than fresh and not tasting absolutely 100% amazing!! Personal preferreances of fondant vs ganach or mousse filling vs buttercream filling aside, your cake should be fresh and moist! dry and cracked fondant or condensation ruining the decoration on your cake is simply not acceptable!! If Disney can not offer the level of service and detail to these cakes as is necissary, than they need to stop offering them/accepting orders! There is no way i would pay $100 for a cake that tasted like cardboard!
and the elaborate decorating is no excuse for the cake to be stale or frozen! The flowers are made ahead of time, not the cake. You don't need to have the cake sitting next to you for 2 days while you make flowers, castles, dinosaurs, or haunted mansion show pieces! Decorations first, THEN you make the cake!
I hope you have responded to the cake hotline, as well as the oerson you were emailing with at the CR to express your displeasure at the cake. Judging by the past cakes we have seen, the CR CAN make beautiful cakes. Someone seriously mixed up your order and you need to be compensated for it! If you did pay for the cake, you need your money refunded!
