There must be a way to book multiple tickets?

Hey, is there a way for one person to choose the quantity of tickets they are booking? 

It seems I have to choose individual registration or group registration.  But I have never seen a website that works in this way before.

Usually I just choose the quantity of tickets I want to purchase.

I'm sure I must be missing something.

It depends on how you want it to work. Maybe you can use Ticket Types, see docs.joomdonation.com/eventsbooking/plugins/ticket-types
