Reno- I don't think open ends would make it an island or a peninsula as long as there was wall space to be related to. I read that we measure along the wall and locate the receptacles on not less than 48 inch centers. a wall space of 12 inches or more would have us relating to the wall space. IMHO. Counter tops separated by a sink or range top are addressed as separate counter tops.
