Hey Victoria,
You are so very welcome! It has been an absolute pleasure helping you.
How awesome is it that you are going to be able to use Disney Gift Cards (DGC) for most everything?! DGCs are widely accepted at many places throughout the WDW Resort. Click
here for info regarding locations that accept DGCs in the theme parks, Downtown Disney (both T-REX & Rainforest Cafe accept DGCs) & the Water Parks. Some carts & other outdoor Merchandise vendors may not be able to accept DGCs - ask before you begin your purchase & there may be locations nearby that carry the same merchandise that do accept DGCs.
Since you are staying off property, you'll also be happy to hear that you can also use DGCs to pay for parking - yay!
I'd probably make sure I had cash on hand when I wanted to grab a quick snack or drink at one of the carts just in case they don't accept DGCs - that way you don't have to go wait in line at a dining location that does accept DGCs. Some of the balloon vendors or vendors that sell all those must have light up thingys at the end of the evening may not accept DGCs. If you plan to drive some of the little remote controlled boats or visit the shooting gallery in Fantasyland, you'll want to have some cash on hand for that as well.
Be sure to protect your DGCs as they are not linked to a particular person like credit or debt cards & anyone can use them. I would suggest making a front & back copy of each & keeping the copies in a safe place. If your cards are lost or stolen, you should immediately contact the Disney Gift Card center at 877-650-4327. You can find out more on the FAQ page on their website - click

Please feel free to visit with more questions. Assisting you with your trip, makes my day! Wishing you many magical memories :-) Allison
