Changes

The right space depends on where one wishes the event to occur. At a University with a big student population it would be important to reserve a large auditorium at which many people can witness the talks from the speakers. Moreover, placing an event inside a building eliminates the risk of possible weather concens such as rain. 

The overall message for the event should be notified easily and in a local area for which the event will take place. At a University creative ideas such as T-shirts for the event and signs can help as advertisement. A TEDx event theme is open-ended. For an innovation theme it would be important to advertise the TEDx event as one that.
