One of my current playthroughs, I still have not had to long rest, and I'm pretty much all the way through the Druid's Grove, including the goblins in the tunnel. Haven't faced the Harpies, but I'm still going strong. I've even still got one more short rest to use and a bunch of healing items.

So case in point. I don't need to Long Rest. Therefore, I will not get a lot of dialogue cutscenes because I'm not Long Resting because I don't need to Long Rest. I'm still on Day 1.
