I love the Event Calendar. One BIG problem that is not so easy to catch. The event calendar allows the user to book guests. Problem is that if the user brings guests, it does not reduce the total count. So fro example, if I have a 35 seat limit, and customer has 3 guests, it only reduces count for customer, but not the 3 guests he brought with him. So event is overbooked. Had to go outside of GHL to account for guests.
