I did a transatlantic on the Grand last month, specifically choosing a Princess ship because I'd seen the "troupe" shows on HAL so many times already. I was VERY surprised to find that the main theater seats less than a quarter of the passengers; and since TA's tend to have more elderly cruisers, they all wanted to go to the early (7 pm) performance. For the big show nights, a half-hour early was not nearly enough; most seats were taken 45 minutes to even an hour in advance of the show. Everyone seemed to have either a book or e-reader with them. The lounge shows were almost as badly crowded, with the additional disadvantage that the Vista lounge has huge pillars that block the view from a goodly portion of the seats. By contrast there was never any difficulty getting a decent seat at any of the late (10:15 pm) shows.
