Guys really many of these are design problems when hotel was commission, build.
Every hotel or place works with something call diversity factors, what are statistic values depending of type of premises, What what they do is incorporate a option or normal operation condition's.
for Water system diameter of pipes and pressure in pipes, and normal hotel load could be like 400 Showers in one given time, possibly only 40 per one rising main water pipe.
Do build building for like 600 showers at time would be huge demand per resources and would incorporate extreme design ( using not commercial, standard assemblies, what would result in maintenance issue cost and availability of replaceable parts)
Same is for air conditioning system they are design similar way expecting certain numbers of people (around 1.5Kw heater, human body) in building for prolong time, if system manage catch up overnight it is fine, but really don't expect to be able cope with 1200 people for 19h in main lobby, and from them 200 active working (producing heat more)
- for showers do take it in different time of day when is less demand if you expect 100% operation, or tell somebody don't use baths, only shower.
- for air conditioning well not much to say unless streets of Magdenburgh could be overrun by furies.
I believe such problems are common at any places with are use 24h as resident area.
