I'd be curious if OP has a partner or roommate at home. When sleeping next to my spouse, I would venture there is some small level of stress associated with not wanting to roll into them, impede their movement, etc. Even just having someone else in the same apartment (different room) I recall being somewhat stressful. When you go from sharing a bed or dwelling to having a whole distinct hotel room to yourself, it can be very mentally relaxing, in my experience. (At least in short intervals; obviously I prefer having someone there with me long term. Although some couples sleep in separate rooms and report very good results!) Interesting phenomenon for sure.
