You can use Event Notes to add extra information to your events without cluttering up your calendar. In the Event Notes editor, you can add and format text in your note as you would in any word processor. When you add a note to your event it shows up as a blue "Notes" link next to your event text. 

You have the option of changing the default "Notes" title to any text of your choosing. See the image below:

By default, if you change the custom title of the blue link from "Notes" to something else, then each new event you create will automatically have an event note with the custom title you created.

If you want to delete your custom event note name you can restore your notes to their default settings by clicking on the red "X" next to your notes in the event editor or by clicking on the red "X" in the "Customize" screen. 

To use the "Customize" screen to restore your notes to their default settings follow the steps in the image below:
