As you can see from my signature, my very first Disney trip is quickly approaching, so I can't offer you any advice from
experience -- but, somewhere during my months of research, I came across the following information, and saved it in my "important" files, just in case. Hope it helps!
Beginning in January 2005, the Camera Centers at each of the Walt Disney World theme parks were equipped with devices to download digital pictures from a variety of popular memory card types and burn them onto a CD. The price for these downloads is $12.99 per CD, but there is a catch - each CD is limited to 120 image files, even if your camera makes files small enough to fit hundreds on a single CD.
As of December 2005, the camera shops in Magic Kingdom and the Disney/MGM Studios both have self-service download kiosks, as does the Kodak ImageWorks center in Epcot's Imagination Pavilion. These machines will also allow you to burn your pics to CD from your memory card for $12.99 per disk. Unfortunately, I have not actually tried one of these machines, so I don't know if they have the same 120-image limit that the full-service downloads do.
Media types accepted for downloads at these locations are:
USB Flash drives (sometimes called thumb drives or jump drives)
Multi-Media cards
Secure Digital (SD) cards
Compact Flash (CF) Type I
SmartMedia (SM) cards
Sony Memory Stick
Sony Memory Stick Pro
Sony Memory Stick Duo (adapter required to use the Memory Stick slot)
Olympus xD-Picture card
