@Sofie Jugard-Lofgren,
I'm not sure how you distinguish between the 2 check-ins, but if you are basing it on an admission item, session, or general question you can use the Invitee and Registrant Details report. There are a ton of report options and a bunch of data fields to help extract the information from your event.
Even the Invitee Summary under reports has a high level of information you may find useful.
Hope that helps you down the correct path.
