Groucho said:My methods and priorities are always evolving. For the last many months I have made no use of overnights whatsoever. However there have been times in the past when I did make regular use of them and things could go in that direction again in the future.
My reaction to this question is, "Even though I may not use them today, I definitely prefer to have them available."
So I guess the answer that best fits for me is "B".
