Wanderfound

I'd expect the lowest possible orbit to be most efficient for the lander. Anything 8km or higher should be safe from intercepting a mountain top. How long are you planning on leaving them up there? If it's a one shot, you probably want equatorial, but a polar orbit may be worthwhile for a long-term orbiting lander base.

...and I noticed this ten seconds after posting my question. Of course. Sorry folks...

I'm getting repeatedly hit with the can't undock bug, but whatever my issue is, it isn't that one. In my files, the "docked vessel" section isn't missing from the subsidiary ship. However, instead of being referred to as "docker"and "dockee", in the equivalent places in my file it reads "same vessel" (in the entry for both ships). Jiggling ships about on other docking ports doesn't seem to do anything useful; it usually just results in more flies stuck on the web. When it strikes, it hits hard: I just had it lock up every port on an orbital facility that had five smaller ships and a three-part in-transit space station parked at it. They're all now orbital sculpture unless I can fix the bug. Anyone have ideas? Should I just go in and substitute "docker"and "dockee" in assorted places?
