You can use Disney gift cards almost anywhere in the parks, CS, TS, snack carts, merchandise. You cannot use their gift cards at T-Rex or Rainforest Cafe, because they are not owned by Disney. So, anything not owned by Disney you can't use the gift card, anything owned by Disney you can and that's most everything in the park. 1. This isn't going to save you a lot of money, but anything counts right? 2. Make sure you have time to have the card delivered to you before your trip. I'd buy it at least a month out or more. 3. The larger the amount the more you save, but it's better to not get more than you need, then money on the card will go wasted. http://www.giftcardgranny.com/store/disney-gift-cards/ I bought a $200 and change gift card for $185. Plan to use it in the parks, and I know I will spend more than that, but I didn't want to spend more and waste money either.
