Hey there — thanks for getting in touch!
Great question. Event Tickets Plus does not actually handle the selling of tickets, but the creation of them. The ecommerce plugin you use is what will handle the sales, inventory and control of sales.
Event Tickets Plus integrates with the following ecommerce plugins:
- WooCommerce
- Easy Digital Downloads
- WP eCommerce
- Shopp
Once a ticket is in a cart, it depends on whether the ecommerce plugin either holds that ticket in the available quantity or reserves it for the person who has it in the cart. My understand, at least with WooCommerce, is that the ticket will be held for the person who has it in the cart, even before it has actually been purchased.
That said, you could do an initial run of tickets then, before a surge, create another run of tickets to accommodate for a period of potential increased sales.
Cheers!
