Also you can always check a guest in by opening the booking and setting the info code "Checkin" in the "Info" tab.
In {{#fas:cog}} (SETTINGS) ACCOUNT > PREFERENCES "Check-in Rules" you can limit the check-in function for the Dashboard modules.
If you use our integration with [[Remotelock.com|Remotelocks]] guests will be auto checked in when they first open a lock.
