Yes, on Partiful events with tickets, guests can purchase up to 10 tickets total across all ticket types per event. In your event settings, you can set a Max per person limit on any individual ticket type to cap how many of that tier one person can buy (see below).
Note: Additional tickets cannot yet be assigned to specific users or plus-ones. Currently, all tickets in a group order will share one QR code at check-in. For example, if the buyer purchases three tickets, they’ll receive one QR code which will check in all ticket types at once.
