We were on the April 27th sailing of the Conquest so I'll tell you what I know. The best seats in the Toulouse-Lautrec Lounge (where the main nightly shows are held) do fill up quickly. These would be the seats near the center of the lounge and the ones with unobstructed views. Even if we arrived close to start time, seats were available on the third level, but these were usually seats off to the side of the stage or behind a column. If you want a great view, I would advise getting to the lounge about 30 minutes before showtime. Speaking of the shows, we were not impressed by the the two main production shows, "Formidable" and "Point and Click". They seemed to lack the energy level of previous Carnival productions. The comedians were great (especially the late adult shows) and so was singer Marcus Anthony. Be sure to check out the entertainment in the other lounges as well; sometimes the best is happening somewhere other than Toulouse-Lautrec. Have a great trip!
