Ticket holder and guest: could you confirm my understanding of the rules?

1 - the ballot gives a prospective ticket holder the chance to buy two tickets

2 - one ticket will ALWAYS be in the name of the ticket holder (unless both tickets are renounced and given back to the AELTC, obviously)

3 - one of the two tickets can be transferred to a guest, even minutes before entering

4 - the guest can enter on their own once they have the ticket, the ticket holder doesn't necessarily have to show up on that day at all

I'm not sure about #4, can somebody confirm?
