Actually, you would get the best photos in complete darkness w/ a flash. Since the room is fairly small -- the camera's exposure and flash will make it seem like the perfect day (w/ no shadows or strange hues from flourescent lights/etc)...Try it out!
Mike, were gonna have to agree to disagree on this one. Show me a side by side comparison of a room where you've taken a picture with the same vantage point and show me how the one without lights looks better. Then I'll give you my final opinion.
