I'm just gonna haul this out when I'm grabbing the trophy. Which will be soon actually! I'm keeping to one settlement. Don't see the point in having multiple settlements if you can fast travel... That's what I've heard Craig, tips like that is what I'll be doing all in one go. Apparently sleeping 24 hours has some sort of effect. I've got 18 settlers with like 30 food and 60 water, 130 defense (all turrets!!) and like 25 beds. Happiness is always in the 80s for me, I tend to go back to Sanctuary Hills fairly often everytime both me and my companion are full on junk (by the way, I'm shagging Cait at the moment...don't know why I find her attractive!!) Having highest level shops with assigned people on them helps (you'll need relevant perks to do this - which sucks balls). Along with assigning people to crop harvesting. But the internet says you have to stay in the settlement and do all this shit for about 4 hours to get 100% happiness.
