I managed to find valid answers but I'm sure some of them are non-unique because they're too easy / obvious. I could have done better but I'm always out of time when I have to babysit my niece.
I really got lucky with the airport one, otherwise I would have invented something foolish.
There were a pretty large amount of invalid answers this round -- it seemed like more than usual -- so make sure to tell me if you're disputing an answer and why immediately so I can fix the leaderboard.
Right after this finishes, I need to finalize the award categories and create that form.
