I have a shapefile of golf courses saved as points, I would like to digitise the boundaries and add the polygons to the existing attribute table. I have opened editor and clicked on the point data shapefile but have no option to create a polygon.

1You need to create a new shapefile as polygon - this can be done in ArcCatalogue or using the toolbox Create Feature Class (Data Management) resources.arcgis.com/en/help/main/10.1/index.html#//…. – Mapperz♦ Jul 26 '12 at 15:51

Your task is slightly more complicated than you would expect. You will need to create a separate polygon shapefile/featureclass. I would approach the problem as follows:
- Add a new shapefile or feature class to your project (right click on folder/feature dataset > new Shapefile/Feature Class... > feature type "Polygon"). Make sure to define your coordinate system if you are working with a shapefile. If you are familiar working with file geodatabases, I would recommend using it to sync the coordinate systems and simplify the area calculations of your polygons.
- Open the editor and digitize your polygon boundaries. Save edits.
- Use Spatial Join (ArcToolbox > Analysis Tools > Overlay) to join the attributes from your golf course point shapefile/featureclass to the attributes of your newly digitized golf course polygon shapefile/featureclass.
If you need additional help digitizing polygons, see this GIS SE link.
