In the vacation time one has had enough time to rebuild fields and meantime everything can be managed with crop from natar and when vacation ends your primary villa has been built up again and you start receiving at least the same and doubled as before vacation
dont definately have to be natar only too..could chief 2 9c villages side by side. Theres lots around usually so take your pick.
The features complement eachother quite well used this way.
I hope i dont have to explain what all comes with chiefing like buildings catas and common sense as you cant relocate having 2 villages so catapult the one down if you have chosen to settle another village for various purposes like another oasis or big party before relocating and chiefing
