But Critical Role doesn't cheese long rests, they just have fewer fights most of the time. There have even been instances where they did larger Dungeon delves...and Mercer makes sure there were consequences for even minor delays, like he hits the players where they live sometimes (the Gboll infested mines with villager hostages near the beginning of Mighty Nein springs to mind: he pushed a full Adventure Fay, and villagers the players had actually invested in died just because they dodged slightly, they didn't do a 5MWD).
