Yes. There are Chase ATMs in both Downtown Disney, Disneyland, and California Adventure. If I remember correctly, the ATMs are located near the lockers in DCA, in the alleyway near the Disney Gallery and bathrooms in DL, and off to the side of the Lego store near the bathrooms in DTD.
This page on Disneyland.com has information about the ATMs, including a map of the locations at the bottom (you have to scroll down on the slide bar to the left of the map to see the DCA, DTD, and hotel information). There are actually a lot more ATMs throughout DLR than I remember seeing! https://disneyland.disney.go.com/guest-services/atm/
