Who cares what other people think, it is none of their business.
I do not always sleep well, so, depening on how I feel I start in the marital bed but when I wake in the night, if it is a wide awake wake, I slip into the bedroom next door, where I can sit and read , with lights on until I fall alseep and the book falls from my nerveless fingers.
The last two nights I have slept in the spare bedroom from the time I went to bed. The first night because DH was feeling a bit under the weather and expecting to be a restless sleeper, and it would bother him, if he thought he might be keeping me awake,. Last night because I was just feeling restless and for the same reason reversed, felt I would be better on my own.
We find hotel room double beds are usually quite wide, two single beds pushed together, or twin beds, so we do not disturb each other and if I wake I sit and read my kindle, without any lights on in the room and it does not disturb DH.
