Yes, eventify allows the option to have multiple tickets per attendee. Here is how you can set it up.
If you have created multiple tickets, all of it will be listed in the ticketing portal for purchase. Users can select the desired tickets and purchase them.
After purchase they will get access to all the sections they have purchased the tickets for.
For e.g.: An attendee who is of type sponsor may purchase a sponsor ticket and also the session tickets if they wish to attend any paid sessions.
Along with users being able to purchase tickets, you can also assign them hidden tickets, directly for a session .
This way an attendee can hold multiple tickets for the different sections of the event.
