The first and biggest thing is that the Wizarding World of Harry Potter is not here. While Potter is an incredible achievement in themed design, it came at the expense of two other great works (the Enchanted Oak Tavern & Dueling Dragons queue). Without its 'Merlinwood' section, the Lost Continent is not really up to being its own island. So, I’m giving Potter bigger & better treatment at a new, third Universal franchise theme park, where the boy wizard will have several new rides & themed areas dedicated to him.
One thing I’ve tried to address at IOA is ride diversity. So in islands with only family rides, I’ve added something for teens & adults and vice versa. Seuss Landing gets How the Grinch Stole Christmas – a coaster similar to Big Thunder in size & intensity, entered through Who-ville and moving in and around Mt Crumpit. There is a kid-friendly dark ride in Marvel Island based on the Super Hero Squad.
Closed attractions such as Island Skipper Tours & Triceratops Encounter are back. The Lost Continent features the opening-day Poseidon show. Dueling Dragons gets much more landscaping around the coaster tracks. The coaster support beams are extensively themed to look like trees or castle ruins. This is no longer a naked steel coaster. Its classic queue is preserved. I’ve added a rather larger & extensive, yet gentle, family dark ride based on the animated film Quest for Camelot (not sure who owns the rights). It is a Disney-style fairy-tale that fits the Merlinwood theme.
