Where are Car Park and Car Registration information stored?

A guests' car registration number and the name of the car park they are in can be stored on the Individual > CRM profile. Should you need this information (e.g. during an emergency) you will find it by running the In House Report.

If you have a car registration number and need to see which reservation it belongs to, you can use the search box in the top left corner of the screen to look for it.
