Tickets may become available at any time.
We can appreciate that this may happen at unsuitable hours, but this is the only way to ensure that they're fairly offered to each person in the list.
If you're notified between 10pm and 8am then your ticket(s) will be reserved until 8.30am. However, if you do click the link between these hours then you will have the usual amount of time to complete your purchase (8 minutes)
If you miss your chance, simply re-add yourself to the waiting list!
Please note, if you are unable to add yourself to the waiting list again, this means that the event organiser has disabled this feature.
