You could try staying at an Airbnb in someone’s home— sharing the living space.
+1. Besides the fewer dedicated resources, a house will have whatever measures the homeowner has implemented to save costs. In Ireland, it's very common to have the hot water heater, and even home heating, shut off overnight. You get a big, fluffy duvet instead.
If you know how to operate them, there are manual overrides for those needing to be up in the wee hours or with health issues. But like so many nudges, it's more effective to opt in to more energy usage, rather than opt out by voluntarily shutting off / turning down the AC or hot water.
I find it ridiculous how often the hotel room is cooled to 60F when I walk in. I immediately go to adjust the AC up to make it inhabitable. How many hours was it being refrigerated like that?!?
