I did that a time or two, until ....
late one night I woke up with an animal walking around right outside the car, it had been raining, so the windows were all fogged up, and things were so tight, I couldn't sit up to really get a look around. I could wipe the fog off the windows, but my light would just reflect back in my face, lighting myself up in the car.
It was such a contortion act, I couldn't get access to get out of the door quick even if I wanted to. I was all shoehorned up in that thing.
Fun and done. I stay in hotels now.
