Yeah, I don't know why they didn't bring the Day/Night cycle and Fatigue mechanics from the previous games, it made resting feel much more natural. You even had inns that gave you more healing depending on the quality of room you choose. I know that the companions say they are exhausted, but they like to do so while I barely done anything and still have most of my resources available. In BG1/2 when I heard my companions complain, you bet I'm looking for a safe spot to rest, Fatigue debuffs were no joke!
