The public in the park and hotel ATM's on Disney property are Bank One. If you have a participating credit union account, you might be able to deposit in one of the public Disney Cast Member Credit Union ATM's (Vista Federal Credit Union).. but you'd need a car, since they are in places like across from DTD, and that backroad over by OKW, and I think in the back of the parking lot across from the Grand Floridian - overflow lot (it's been a long time, don't quote me on that one). They have some agreement w/ other credit unions, because I can deposit in the local credit union by my house.. which is nice since I don't think there is a Vista outside FL or CA!
Where are you staying? We were at the contemporary in december and they have much newer, and wicked cool safes in the rooms. They are electronic and you set the code yourself or use one of your credit cards (it doesn't charge it, just uses it as a unique identifier to open/lock the safe) I liked it much more than the kind with the key, which I'm constantly worried about losing. We used it the whole trip and didn't have any problems.. jewlery, ipod, video camera, psp, a few special pins, and all the gift stuff. DH even wanted to put his laptop in there!
