Hi Erwin,
Thanks so much for reaching out and for your interest in our products!
With Event Tickets Plus, users can purchase tickets to your events. You can create a fixed quantity of tickets, so that users can book tickets to a capacity for the event.
If you are looking to book a facility, I suppose the best way to accomplish that would be to set up a single ticket for each time slot.
It’s also worth noting that we do have a Nonprofit Partnership Program, where we provide free Personal Licenses for Events Calendar Pro and Event Tickets Plus to approved nonprofits.
You can apply here if you’d like:

Let me know if you have any other questions!
Thanks,
Jaime
