Do they split a group of two up? I read many complaints of couples being broken up in there Also, what do they mean if you don’t make it through they are no refunds?

They will split even groups of two up. I went with my boyfriend and we were split up until a bit before the end. If you are thinking of this as a first date, it's a terrible idea. In terms of your second question, they have a high quit rate. That means, a lot of people go in but don't make it all the way because they are frightened and quit. So you can't get a refund because you decided to quit 5 minutes into it.

If you tap out you can leave before making it through, but your not getting your money back. And yeah they will split you up if they know you're together.

You can call to quit if you get too frightened. And yes you do get split up but you do end up at the same place.
