Hi Mike,
Thanks for checking out our plugins!
Events Calendar Pro does come with single venue and organizer pages which include info on the venue/organizer and the upcoming events for that venue/organizer.
By default, there is not a way to prevent an admin from editing a venue created by another admin. If you go with Community Events, which allows users to submit and manage events from the front end without having to have admin access, we do have a freeĀ extension that will prevent users from seeing or using the venues and organizers that were created by other users.
We do offer full refunds within 30 days of purchase, so if you’d like to take Pro or Community Events for a test run, feel free to do so! Please let me know if you have any additional questions.
Thanks,
Jennifer
