Using Disney Gift Cards

[Fredericks44]

Hi fellow mouse lovers!
Question from a newbie. I'm considering buying many disney gift cards from target due to the red card discount (covered in another thread).
What is the ease of which we will be able to use them? Can I charge everything to my room and then pay the balance with the gift card? if i go to my local disney store can i consolidate all the cards onto one? i want to save some money by doing this but I don't want to spend my much anticipated vacation fumbling with gift cards.
