Gift card for prepaid events?

[TISHLOVESDISNEY]

(I apologize if this is wrong forum Mods!)

I booked EMM for July, but it would not allow me to use my gift card. Does anyone know if I can call in and do this? I have quite a bit of $ combined on GCs in hopes to use them for EMM, and dessert parties. It'll be a bit frustrating if I over budgeted with GCs...
TIA for any help

I'm pretty sure you can call in and pay with gift cards.
