Problem:
How to properly create "Event" custom post?

Solution:
With Toolset, you can multidate events using two date fields start date and end date or you can use repeating date field to assign multidates.

Toolset offers free test platform http://www.discover-wp.com where you can find number of reference sites:
=> https://discover-wp.com/site-templates/

I suggest you should visit any of reference site and learn how those are made by creating a test site for you and try to create event post type and few custom fields and if you see it works for you, you can go with Toolset.
