I was going to write something to limit travel to camp at anytime because it's not realistic to be able to run to your hideout from any depth.
Camp reminds me Dragon Age origins' camp , because they act very similar, - not a bad thing - you talk with companions, rest then go adventure. But here the problem is you can go the camp from anywhere and from any situation.
It was limited in DAOrigins thought it also made very tiring area transitions just to make camp button available.
So your suggestion solves them both, maybe with a in game cooldown or so our perfect escape ability can be both balanced and not immersion breaking.
He who fights with monsters might take care lest he thereby become a monster. And when you gaze long into an abyss the abyss also gazes into you.
