Makerble allows you to collect two types of Event timesheet
Guest timesheets - to record how much time a guest (contact) has spent at an event
Staff timesheets - to record how much time a colleague (in their capacity as Event Worker or Event Manager) has spent at an event
Information from both types of timesheet is accessible from the Manage Timesheets page
