Has anyone ever asked the Apollo astronauts what altitude was best for viewing the Earth? I imagine sitting in a lounger with a drink in my hand, looking out the picture window view port at the Earth. What hotel should I choose? The one located at LEO, half-synchronous, GEO, or high orbit?
According to Heppenheimer, Colonies in Space, Chapter 8: The Highest Home,
the best orbit is a 2:1 resonant orbit. In http://www.nss.org/settlement/ColoniesInSpace/colonies_chap08.html
"Such an orbit is the preferred one for the colony, since it can be reached from L2 with very low velocity and also reduces the velocity required to reach the colony from Earth."
The colony varies in distance from Earth from 100,000 to 200,000 miles.
