And that's kind of non-trivial from where I sit.
I never said it was trivial. What I was saying is that people don't need maps to navigate every complicated space they find themselves in. No matter how complex and 10 acre corn maze is, I still bet most people can navigate through it given enough time. Time is non-trivial, but it also isn't exactly of dire importance when you are talking a few hours.
The question is whether you're even up to killing the things you hit after two hours. You don't need to get into old megadungeons for there to be one with 20 potential encounters in one, and 2-4 of those may well be all you wanted to really deal with without a chance to recharge by themselves.
Maybe, there are numerous parts that can be adjusted here, from level to enemies to abilities available. But, here's the thing. Lets us say that there are 20 encounters, and there are 5 enemies per encounter. That's 100 enemies. After you kill 100 enemies then... you should be able to take a long rest in the area, because there should be nothing left. And sure, maybe you get 20 enemies in and want to take a short rest, but what I've tended to notice is that after enemy 100... they find another random encounter with 5 enemies.
Also, some things just don't make a lot of sense. This is the common dungeon ecology problem, but even in the wilderness this would crop up. Logically, an owlbear should have about the same territory ranges as a bear. That is 120 to 300 square miles. That is, what, six days of travel? If in one day you meet two owlbears, okay, maybe they were a mated pair. But if in the same day you meet four or five owlbears? That feels wrong to me. That would mean that these massive hunters have been all hunting the same stretch of 20 miles. That's insane.
It is why I get a little annoyed when people say that characters can't rest or take a lot of time, because they will be attacked. At a certain point in time, you've killed enough things in a small enough space that there isn't anything left to be dangerous.
