I will sleep the night early game, until I get iron and then I go out serpent hunting.

Each biome I am pretty careful of until I gear up past it, then I am not too worried about night unless I just want the light to see for crops or building. Once I have my gear and skills up the only place I avoid at night is the plains. Oh I guess I won't mine at night either. For me it isn't for roleplay, just being practical/safe.
