I believe it is Dazzle that makes a device that has a built in 6-1 card reader, with a combo Hard Drive. The cost ranges from about 250-400 depending on the retailer and the HD space, but it is about the size of a CD jewel case, and weighs a couple lbs. It would be easy enough to put it in the safe of your hotel, and DL all the pictures at night. It can also minimize the amount of stuff that you end up bringing to the park. Check CompUSA, Best Buy, Circut City, or any high end computer electronics retailer. Camera stores too.
