Yeah, and that's the fault of the game designers, not the DM. The game designers should not force the DM to make a choice between breaking the fourth wall, throwing out a common and plausible adventure design, or hurting game balance. It's a choice that was never appropriate for the game to present, and understandably a lot of DMs are going to decide on 'there isn't going to be an hour of downtime between killing the evil king's generals and confronting the evil king in their throne room'.No, the guidance is not wrong. If the DMG recommends doing something a particular way and the DM decides to ignore that guidance, they should know there's going to be a problem. Which stunningly enough, there is.
Now: this is not even really a big problem for most classes. Except for the monk. A Warlock or a Fighter can still go on if they have to do two or even three combats without a short rest. The monk's the only class that makes it a big problem, rather than an annoyance. If the monk had more ki points or long rest resources to tap into, it'd just be an annoyance more impactful for some classes than others, rather than a game balance issue.
