Hi Francois,
Thanks for checking out our plugins!
Event Tickets Plus does not currently have the ability to set different pricing for members. However, tickets are essentially WooCommerce simple products, so WooCommerce add-ons typically work pretty well with tickets. To make sure that it is going to work the way you want it to, you would really need to test it out.
Event Tickets Plus does come with the ability to add custom fields (like text and checkboxes) to tickets, allowing you to collect additional information from each attendee.
We do offer full refunds within 30 days of purchase, so if you’d like to take Event Tickets Plus for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
