Hey @Kenna,
You unfortunately cannot do this at this time unless you were to write some extensive custom code 🙁
We cannot help with custom coding (check out the “Product Support” section of this page for more information → http://theeventscalendar.com/terms). However, can you describe a bit more about who the “certain people” would be in your case?
Based on your use case, I will try to recommend some custom code if possible! 🙂
1. For example, is this as simple a distinction as non-registered users will not be able to see the ticket form and buy tickets, but users who have accounts on your site can buy tickets for events?
2. Also, is this a universal “limitation” for all of the events on your site? Or will only certain events be “exclusive” in this way?
Thank you,
George
