I may not know as much as I would like about orbits, but I would think we can find an orbit compatible with interplanetary journeys that we can service from the Earth without too much difficulty. Wouldn't any realistic Mars transport ship for Humans have to be assembled in Earth orbit anyways? I'm thinking it'd be nice for whoever is doing that assembly to have a nice station to live in instead of some kind of tiny disposable capsule.
