If you look up from here you will see the world's tallest rollercoaster and above that is this insane air chair ride that lets you free fall above the whole city. Near some elevators in the Stratosphere Casino. These are gold. In the shops area of the Stratosphere Casino. These are down a hallway to the restrooms near Planet Hollywood.
All phones are gold.
While getting these numbers I noticed thse phones looked right into the the ladies restroom, which I thought was a little strange to see. From here you can see all of Vegas. Here you can hear the rollercoster above you as it shakes the tower when it goes around. Very cool location, it's full of waterfalls, trees, fish tanks and fake animals. These phones are all gold plated.
