I've always been told it was cheaper to maintain than to cycle on/off within a day as long as the insulation is decent and you aren't trying to get to 60F during 100F weather. My guess is that comes from a belief that the units work inefficiently to get the temp down as fast as possible when turned on, but work more efficiently to maintain a temp, but I have no idea if that's true.
