If I were the boss, I'd do a giant, unique nighttime spectacular in the lagoon (World of Color quality or better); a few place-making improvements around the park (similar to what they did with Springfield in the Studios)--in Jurassic Park especially, replacing the Trikes with a family-based ride and a flat ride or two; add something major to Seuss (I'd go with the Mt. Crumpit coaster, but a family dark ride would probably be the better choice), and lastly, I'd level the Lost Continent and replace it with something relevant. I'd also focus on improving the quality of the food in the "regular" (non-special) venues, like Comic Strip Cafe, Circus McGurkus, etc. With that, I feel that IOA would be in excellent shape.
