You can use this bit of code in the Event Description area on step 3. Configure Additional Information:

<style type="text/css"><!--
#sidebar-second {
margin-top: 0;
float: none;
position: absolute;
top: 160px;
right: 0; }
#lo-CalendarDateInfoContainer { display:none; }

This will hide the Event Date that normally displays at the top of the Event details page.
