Sorry it took so long to respond to on here!
So we called the gift card number yesterday to try and combine the money on all one card...no go. The lady said it was not able to be done. Called the resort and the man said they are only allowed to take 3 cards over the phone?!?! Never heard of that before. Called every Disney store near us, and they all carry nothing under 3 day. Of course grocery stores have them, but they probably won't take the gift cards, just like Red Lobster wouldn't take an Olive Garden card. So I guess we are stuck buying them at the park.
