You can see the very top of Everest from some locations on the 6th floor of Jambo House. Twice we've stayed in the room closest to the elevator on the DVC 6th floor (overlooking the pool), and we can see the tip of Everest clearly. It's actually a bit easier to find it at night because of the way it is illuminated. In the morning or at night when it's really quiet, you can easily hear the people screaming on the ride too.
Having said that, we haven't been there since 2014. I'll let you know in March lol.
