Our honeymoon cruise, my dw and I took the later seating. We are both young, but had hoped to avoid the chaos we thought familes with even younger children may cause. Kind of shortsighted of me I guess because we had the main seating on the 2nd cruise and found it to be more peaceful, granted this could be a limited experience, but who knows! We asked for main seating this time (honestly it didn't matter to me this time, but the in laws liked eating earlier) but we received the second seating.
Hope my rambling is intelligible enough to understand! lol
