I don’t know what it is about sleeping in a hotel. I do it fairly often and almost every time I wake up with a real kink in my neck and some degree of a headache.
Also, would it kill them to put a few humidifiers in? It’s always so dry. My mouth and nose kill in the morning. I’ve turned to running the shower full hot for a while before bed most times. It helps but it’s not perfect, and a waste.
