Frankly, a quick queue at sea world is rarely necessary for anything. If you apply a Disney-like itinerary and strategy to the park you'll be like a hundred gazillion light years ahead of the rest of the visitors. Reserved seating is just not necessary at any of the shows except maybe sea lion and otter, but for that show you want to get there 15 minutes early anyway because the pre-show is as good as the main show!
As for "rope drop", there really isn't one here. The whole parking and entry situation is very chill. They just hold you at turnstiles then let you in. The wait shouldn't be any more than 10 minutes, maybe 15 for the first hour of the day at emporer tbh.
