Last October, we were about to spend $100 on a new memory card at the photo store in EPCOT (too many princess breakfasts!!)

when the CM mentioned that for a few dollars (don't remember the exact amount, but I think it was less than $10) they would burn all of the photos from our memory card to a CD. So, we turned in our disk and went picture-less for four hours, and then voila - we had a CD with all 70+ pictures on it!!
I did check the CD to make sure before deleting the pictures from my camera, and then started by deleting the less "valuable" pix first, just in case, but I had absolutely no problems.
We're going again this October and plan to do the same thing, rather than spend $$$ on a card that will only get used when we're on vacation. I'm pretty sure that they have this service at the gift shops at WDW hotels as well. I'm sure that it's a service that will be expanding, rather than declining, given the growing numbers of digital camera users.
Hope this helps!!
