The snowball schedule attached below has organization by the use of hierarchy through color and font. The use of the different fonts for each event (some larger than others) creates a hierarchy of importance. Also the use of two different tones of blue for the different locations is successful. The ribbons that include the dates is also a good technique to bring that information to the foreground. The image behind the title, location, and date creates depth and is overall successful because of the use of minimal color.
I think this particular schedule is successful. The only thing I would change is the use of all the fonts. Some people might find this distracting or confusing; I don’t feel this way. The use of the different blues is what I feel keeps the schedule unified.
