Ordering birthday cake

[ColoradoDisneyFan]

I made my Toledo reservations weeks ago and wish I had ordered a cake then when it gave me the option. How do I add a cake to my existing reservation? I cannot find any options to do that. TIA

Try making a new reservation and add the cake with the new ADR. Just make sure to cancel the original reservation if you make a new one.
