Hi, I am also exploring a number of issues about data transfers from CAD (Autodesk Civil 3D 2013, 2014) to ArcGIS 10.1, am looking at forums today to see where are people doing same tasks, looking for some guidance myself.
I believe the answer to your question is NO, you are going to get the polylines and the polygons (and more), but once you are there at that stage you can export either or both of those in the data format you choose in ArcGIS.
However, I am not sure exactly about details of process you are using.
