Honestly I still keep my elbows up high on front squats. That whole "drop them" advice made my wrists hurt and my chest cave in. Maybe it works for some bodies, but for me it messed up the whole groove. High elbows keep my torso upright and the bar locked in place. I'd say stick with what feels strong and stable for you.

Have you brought up the sediment issue with the hotel developers directly?

Composting toilets sound great in theory, but who has time for all that upkeep? Vent fans clogging every week, messing with peat moss on weekends, that's a part-time job. Why bother when a flush toilet just works? The ammonia smell alone would drive anyone crazy. Sometimes simple is better, and you can't beat the reliability of traditional plumbing. Who wants to spend their free time playing toilet technician?
