Windows in a spaceship/station are a bad idea. The first micro-meteorite
to come along would completely ruin your dinner. Besides, there's
nothing to see except the planet, and depending on what orbit your
HighPort is in, this might be pretty small. Internet searches suggest
that the Earth subtends 17 degrees from geosync. By comparison, the Moon
subtends half a degree from the Earth's surface, and the Earth subtends
around 1.5 degrees from the Moon (think of the famous Earthrise photo).
You certainly wouldn't see any stars. (I was too lazy to check any of
the math so YMMV).

So what's the answer? Videoscreens. You can set these up to show stars,
zoom in on the planet, ship traffic, anything you want. After all, the
AI running the station is bored and has nothing better to do than
entertain the paying customers, right :-)
