...jk ;), though you can probably get some info from people on this thread who are either from there or traveled there
Not sure of your expectations, but Ninh Binh is limited for expat living.
Since you'll be working during the week, you could use you're weekends to play golf? http://royalgolf.com.vn/
Other than that, your limited to several tourist attractions: http://www.dulichninhbinh.com.vn/en/
Having been there several weekends, and also passed through regularly. I found it was just an overnight, possibly 2 night stop off on the tourist route (North - South - North). So you will find some people to talk with, tended to notice the hotels down by the train station with the most tourists in them.
Other than that, we found a few decent cafe/bars and one nightclub, but neither littered with expats.
Personally if i lived there, and work was Monday to Friday, i'd be in Hanoi for the weekends, buses are plentiful if your not to fussy on standards.
