Can I bring a friend without a ticket?
No, everyone attending a Thursday event needs their own valid ticket, so you cannot bring a friend who does not have one. Every guest needing a ticket is how we keep the gender balance and group size right on the night.
If you would like your friend to join, the best thing is to book together so you are both confirmed. If tickets for their group have sold out, keep an eye on the event page in case more are released.
