Hmm, docking ports, interesting idea, assuming ofcourse the particular model I'm using has them. I always assumed the base was much larger than the connie, because the ball shaped bases in TNG are basicly the top of a regula one, I allways assumed they were the same thing. I wonder of those dimentions (besides the width ofcourse) apply to the obital office complex, or if that was a scaled up regula one as well? I don't believe there were ever any ships close enough to it to get an idea.
