This was on the Magic on our WBTA in 2010. It was located on the port side, aft, just inside the covered area on deck 4 (don't know if that's where it always is, though):
I believe that was on deck 4 starboard side forward. just when you entered the covered section on the jogging track. The top pic is looking back towards the rear of the ship if my memory serves me correctly.
