Best solution for field combining? (for event management)

Hi, everybody,

I am researching the best solution for event handling solution. I need some kind of field combining (or?). The result should be something like this:

Event_A
date_A, place_X
date_B, place_Y
date_C, place_Z
Some basic info about event_A.

Event_B
date_D, place_Y
date_E, place_X
date_F, place_X
Some basic info about event_B.

What would be the best solution for date and place combining?

• Should I use some kind of field combining solution?
• Or should I create one content type for events, that would be the hub and contain all basic event info (also comments and so on). And other content type that would have reference to event but also add date and place info. And then displaying the event also output all dates and places that match the event.

Currently I am working on D7, but I would like the solution to be future proof (D8).
