Can I split a ticket so that one person participates on the first day and the second person on the second day?

No, all tickets are personalized and are non-transferable once they have been accredited.

However, you can transfer your ticket to another person at any time up to 2 weeks before the event, free of charge and without any hassle. Go to your myOMR account and reassign the ticket.
