I have multipoint features.  I want to convert this to polygons. 

I used the following tool using convext hull, but I'm missing areas.  See picture.

Minimum Bounding Geometry—Data Management toolbox | ArcGIS Desktop 

Is there a tool or ArcPy way to get the polygon boundary of the multipoint feature?

Peace & Love!

If you are referring to the areas marker with the blue polygons:

... then that is normal when creating a ConvexHull. 

It seems that your points are evenly spaced, so you could consider converting to raster those points (using the spacing between the point as cell size) and then convert the raster to polygon.

What you are looking for is the 'concave' hull there are few implementations readily available for arcmap, so Xander's approach is the best to go with
