Which calendar plugin to choose according to the right conditions?

Question

WordPress

The task is such that it is necessary to display columns on the page - days of the week and time in rows. There will be classes in the cells, that is, almost usually a class schedule. But the “almost” is this: when you click on a lesson, you can sign up (reserve a place) and not just one, but as many as will be indicated in this lesson (5.10 or another number of people). It is also necessary to somehow store people who will sign up for a particular lesson.
As a result, there should be some kind of grid in the admin panel where the admin could schedule a week and then it could be displayed on the page without any problems (ideally drag-and-drop, but this is just an ideal option, at least something simple for now) , well, the booking system for the same cell is several people, as the admin indicates.
I have already reviewed a bunch of plugins and even I don’t see a suitable one, maybe I’m looking for a felt boot, or maybe there’s no such option in the print.

Answer 1

I don't know if you will find a ready solution... But I would recommend you to find a JS developer.
Let him write a small plugin or mu-plugin for you using Data Tables.

Answer 2

For these purposes, the Event Manager plugin is ideal.
