The walk from the Santa Fe to Cafe Mickey at the start of the Village is around 10 minutes once you are on the pathway over the bridge between the Santa Fe and Cheyenne hotels

. From the Santa Fe bridge coming back from the Village you'd go up through the Santa Fe hotel blocks, past the road entrance, and turn left past the filling station. The Dream Castle is next to the Explorers hotel in the row of 4 hotels, so I'd say another 10-15 minutes from the Santa Fe to walk to the Dream Castle.
