They do not rush you at all. I've been there in the line after midnight and we did both the house and the forest. Maybe it's changed since then. But they still never rush you. You go at your own pace.
If you are in the ticket line before midnight you will be allowed to buy your tickets. You will not be rushed through the attractions. The forest and house will stay open until everyone that has a ticket has gone through.
You only get to choose one, if it's midnight and you want to get in both of them
