Hey Craft, glad to hear you're enjoying the game.
While we will add more management days to future builds (there's a ton of content now and very little time to do everything because we're future proofing it for when players have more time) there still won't be enough time to do everything, and the Hinterlands 7 day limit is fixed.
We discussed this a bunch of times on the forum but our overall design philosophy with Minotaur Hotel is that if there was an optimal way to do everything and recruit every staff member and complete all the character routes and do all the hinterlands quests, etc. then there would be no reason to do anything but stick to the optimal route. It gets players in a mentality where they check items off a list and don't really get immersed into the story. While I understand the frustration of not being able to do everything on one go, I think it makes your choices as a player more meaningful. Hope it's not a dealbreaker.
