Display labels only to specific cities in Google Maps

Question

I have polylines connecting two points on the map. I want to display labels only for those two points, and hide all other labels.

I have explored the Google Maps API to see how Styled Maps work. Using the hiding features, I could achieve hiding and display of labels at various granularities, but what I fail to achieve displaying only two city labels.

For instance, if I have a line connecting, San Jose and New York, only San Jose and New York labels should be displayed on the maps, with all other labels hidden. Currently what I see is that I can hide labels at administrative.province level, but it hides San Jose and New York labels as well.

Here's a snippet of code that I have for polyline and hiding some features.

I don't think there is a way to be that specific. You could create two markers with infowindows. Not really the same but that could be a solution. — MrUpsidown, Apr 26 '15 at 17:49
Hide all the labels. Add labels for the two cities you want to have labelled.

@geocodezip There are no examples cited in those posts. If you are aware, of any complete examples, could you please let me know. — ATP, Apr 27 '15 at 03:37

Example from Google maps hide smaller cities (localites) with your code/polylines:

function initialize() {
  var MY_MAPTYPE_ID = 'custom_style';
  //var MY_MAPTYPE_ID = google.maps.MapTypeId.ROADMAP;
  var featureOpts = [{
    stylers: [
      //     { hue: '#890000' },
      {
        visibility: 'on'
      }
    ]
  }, {
    elementType: 'labels',
    stylers: [{
      visibility: 'off'
    }]
  }, {
    featureType: "administrative.country",
    elementType: "labels",
    stylers: [{
      visibility: "off"
    }]
  }, {
    featureType: "administrative.locality",
    elementType: "labels",
    stylers: [{
      visibility: "off"
    }]
  }, {
    featureType: 'road',
    stylers: [{
      color: '#00FF00'
    }, {
      visibility: 'off'
    }]
  }];


  var mapOptions = {
