Plymouth, Massachusetts. We were here in 1985 and again in 2010. I have good video from 1985 with people eating outside with a guest from England. The people stay in character at all times while talking with guests. They speak in Old English and only talk about the events of that day, on that particular calendar date in history. They will give information about their trip to the New World and the challenges of being there. The best time to go is around Thanksgiving. They have a lot going on with kids playing, dinners, and workers all around.    
They actually have gardens and cattle, and sawmills and a working brick kiln where the characters work every day. They live like they would have in the actual colony. There is a native village on the edge of the compound where they still string beads and make garments and replicas of their dwellings.
