Multiple dates on Event (custom post type)

Hello!

Im about to develop a site shall list courses,
where each course will have multiple dates. I have set up a custom post type
called ‘Course’ which will hold Title, description, categories and hopefully dates.

The problem is that I don’t know to apply more than one date to a single course.
To demonstrate the structure that i’m after, here is an example of a course:

Title: Mastering photoshop
Content: This is some text about the course!
Category: Computers->Photoshop, Photo
Dates:

Date 1: [13-15 apr + 17-19 apr]
Date 2: [3-6 oct + 8-11 oct]
Date 3: [7 nov + 9-10 nov + 13 nov]

As you can see, each course can have multiple dates,
where each date can have more than one instance,
where each instance can mean more than one day.

A “customer” have to select one of these three dates.

There are no demands of any booking functionality at this moment,
but you should be able to set a date to the status ‘FULL’.

All this must be easy to manage even for a non-technical person.

So, do anyone here know of a plugin that does anything like this,
or do you know how to solve the problem in any other way?

Tips, questions and any help are very welcome.
Thank you!
