Essentially I want people's thoughts on layout strategy.
It struck me that room upgrade prices seemed cheaper (on a per dweller slot basis) when upgrading a combined 2 or 3 room room. Said differently, there's bulk discount pricing. For instance it might cost 250 to upgrade a single water production room but if it's two combined it might cost 375 (a savings of 125 caps). That encourages larger rooms.
But there's risk with that. If you moved people around then a combined room of 3 diners may only have 2 of the 6 (3 rooms x 2 dwellers each) possibles dwellers. If the room gets attacked it will still get attacked by 3x the normal roach amount. End result is vulnerability that can lead to death or at least high health loss when're rooms aren't fully staffed.
Questions:
What strategies are people using to best maximize production, minimize cost, and minimize attack risk??? More rooms that are small rooms or fewer but larger?
What room is best to put near the vault door to protect from raiders? The strong people (power plant people). Or endurance types… Are they tougher?

Ok, I will address the issues as I come across them:
