If you'd like to create a discounted ticket for two or more children or friends, you can do this by creating a group ticket.
To set this up, head over to your entry and select Edit Entry then under Tickets & Costs you can create a new ticket type for each sibling or friends ticket you would like to offer. The booker then only needs to select one ticket that covers multiple attendees at a set or discounted price, for example:
In this example, the ticket cost is the total cost for two children, and the group ticket option is ticked and set to exactly 2 children.
Here's how this example looks on the public booking page:
This same setup can be used to offers like bring a friend for free or twin tickets etc.
