Can I see ticket type on an opportunity?

Events Made Easy (Eventbrite) can create opportunity records but these are based on order records.  The ticket type is stored against an attendee record.  An order can be made up of one or many attendee records, with one or many ticket types.  So for this reason it is not possible to store ticket type on the opportunity record.  

However, all of the information is stored in a structured way in Salesforce so you can build your own reports and report types.
