Oh yes, I will have to look it up, but we are about in the direct center of the ship, which is a good place to be if you have not gotten your cabin yet. It really does not matter which floor level you are on, just as long as you are located about in the center of the ship. There is not much movement really, but you can sometimes tell it is moving up and down if you arent in close proximity to the center - especially if the seas are a little rough.
I have found I am rarely in my cabin, except to sleep, shower and change. So, I generally opt for the lesser expensive cabin in the center without windows (you can't see much from them anyway unless you pay $$$ for a suite with a balcony). I have paid the extra for windows, etc but was not in my room enough to really make that much of a difference to me.
