On the original subject of this thread, namely strategy for maximizing income...
I have just purchased Ms Mouse and the 2nd quest in her story line involves an 8hr task which pays out 120 foam knives along with a 12hr task for Mayor Quimby.
If you do NOT complete the Quimby task, then Ms Mouse's 8hr task can be done repeatedly giving you a better alternative for overnight missions than just sticking everyone on 4hr "Staff Rides" at the gate for 72 foam knives each.
Not a huge difference, I know, but an extra 48 Foam knives every night for free might just get that last prize or extra Donut spin for somebody.
