The buffet diner off hours sounds good, you can also try the upper seating area of the buffet dining. There is two levels of outside deck on the very front of the ship not many people know about. You can only access it from the hallways of the passenger cabin area . I "think" its like deck 7 or 8 way up front. If the ship is moving, you MUST be very careful opening the door for it is very windy up there. At night it is very dark, great place for veiwing the stars. Good Luck on your cruise.
