You can use a vertex type with info but not insert function
taking an interator over point and info is available.

You need to set them by hand like this for example:

Vertex_handle vh=cdt.insert(pt);
vh->info()=5;

If you have a performance issue, you must use spatial sorting first has
done in the implementation of insert-by-range in 
CGAL/Delaunay_triangulation_2.h
