Yup! We have been racking up Disney giftcards for our September trip. We are paying for all of our food.. TS, QS and snacks with giftcards. We are buying them at Sams and Target to take advantage of the little bit of savings.
We have 3 room reservations, myself in my own room. We are all buying our own. So when I am finished buying giftcards I will merge them all to one on disneygiftcard.com. So I plan on having 1 card for food and 1 for souvenirs. So much easier merging them, than having a whole bunch to bring and figure out which ones are used and aren't.
