Good points! I'm not sure how interesting the clouds would look. There is definitely some dynamic behavior there, including electrical storms, and you'd have a day-night cycle spanning 4 days total, not due to the rotation of Venus but rather the atmospheric dynamics.

Also keep in mind that due to the dangers of radiation, the denizens of a lunar or Martian colony would not be outside that often. The most realistic plans I've seen actually have the habitats completely underground (e.g. in lava tubes on the moon [1]). Certainly a few of the colonists will leave on science missions with some frequency, but the vast majority of the time people will be inside and underground, albeit probably tele-operating mining equipment and things like that in many cases.

I think if you think big enough, in both cases the problem isn't that bad: being in an underground habitat / cloud habitat the size of a small town will feel like you're on solid ground, not like you're in an airplane in the clouds / in a cave. Artists and architects can design artificial landscape to keep things from being boring.

Judging from the happiness of my fellow city dwellers when they hang out in the mall, I suspect that colonists would not mind being inside as long as there was enough shopping.
