You can plan all you want, but if you don’t have attendees, you don’t have an event. As we discussed earlier in the previous blog entry, How to handle event budgeting?, attendee fees is a fundamental issue for the budget.
If you decide not to have a fee for your event, you may consider a no-show fee. A no-show fee is charged from an attendee that has registered, but doesn’t for some reason show up. In case there’s no possibility for queue lists for your event think about having a no-show fee, that way attendees won’t just disregard your event even if they’ve registered.
