Our events are sometimes complicated and have multiple parts each with their own deadlines and prices.
For example, we might have a conference over two weekends, but we don't want to make it look like separate events by creating two events in Constant Contact. We only want to create ONE event. However, weekend 1 has different early and regular deadlines than weekend two.
I don't believe this is currently possible to do with Constant Contact, but that ability would make Constant Contact's event management useful to my organization.
