I never got to see Turtle Reef before the updates, do you have any photos/videos?
If I had to guess, the shark and penguin encounters haven't been touched since at least the 90's, maybe earlier. I think the shark encounter is long overdue for an upgrade, but I'd want to see it
upgraded, i.e. more like the aquariums at SeaWorld Abu Dhabi, not downgraded to some sterile airport-like aesthetic. Whether that means just fixing the fake sky ceiling (maybe replace it with a projector screen like the bug exhibit at the San Diego Zoo?) and dusting off the fake plants, or doing an actual expansion and thematic upgrade, the end result should be
more immersive, not less, to meet the standards being set by other parks and aquariums--including other SeaWorld parks.
I also still really think the penguin exhibit ought to be moved next to Emperor, since it 1) needs to be updated anyway, 2) belongs next to the penguin ride, not the Arctic ride, 3) would be a chance to properly build out Emperor and the area around it, and 4) would free up a lot of space for something else if the gift shop building were removed too, even more if the event space next to that were relocated. This seems somewhat relevant right now because the park appears to be shifting things around, presumably to make space for new additions. If you'll excuse this very basic illustration, it seems like an obvious move would be to turn the pathway and plaza between JTA and Emperor (white) into an icy-themed mini land and build a new penguin habitat either behind the ride (light blue) or integrated with the queue like Manta (dark blue).
