I think Toon Lagoon needs to go. None of the rides or attractions match the show quality of the rides in the lands between them. Kids hardly know any of the characters.
You know, after my most recent visit, I think Universal needs to set a standardized level of quality across all ride, shows, attractions and buildings, because with them going in for the kill on almost all of their recent attractions... The holes are becoming more apparent, across both parks. Diagon is beautiful, then you explore the rest of the parks, they are still stuck in that 90's park look. The LOOK of the parks needs to be updated to keep with the times, along with the surroundings. They need to refresh and redo small sections around the entirety of both parks.
Toon Lagoon Retheme. 3 New Attractions, replacing Dudley, Popeye's and Toon lagoon Theater. 1 attraction that's wet. Popeye's area is big enough, it could be it's own land, taking on the land design schema they've introduced with Diagon and continued with Epic Universe . If they went for a multi-level land, I think they could squeeze out the amount of surface area in that area that takes up the entirety of Diagon Alley, including the gringotts show building and kings cross... They have space in there. They could also use a portion of that hypothetical new land for storage for a lagoon based nighttime show.
New Dark-Ride for Dr. Doom area. I'm thinking something like Marvel's Haunted mansion or something. Super-Hero Island updated to more modern versions of the comic book characters.
New Dark ride for Lost Continent, where Sinbad sits. Something like Journey to Atlantis, so there are water ride options on both sides of the park.
JP is always and forever in my heart, But my opinion has shifted on what JW would look like in islands. Do the whole JW thing, upgraded discovery center, But I would leave out the scene with the mosasaurus... Maybe start off in the aviary and have a first close call with a pteranodon? It'd be funny,they can play off how something always goes wrong in their attractions by having something go wrong with each scene. Add something (i.e Falling Gyrosphere maybe?, swept off a cliff by indo tail?) to the back half in the containment area.
Also, really... They need to go back to both parks for HHN and they just need more event packed in their event. Whatever they have to do to get Potter in HHN, They need to do it... It's obvious with the Dark Arts show that "Dark Potter" would be the biggest thing they could ever add to HHN, and people would line up yearly to get a chance at seeing it. Considering it's a limited time, separately ticketed event, they would have people rushing every single year to book . Seriously, if they have to create new footage for the train (both ways), overlays for Hogmeade and Diagon that can be switched out in an hour, as to not disrupt normal daytime operations... And do much much more, that price tag would be worth it, as it seems the result would be similar to when they opened Diagon. Guest haven't had the chance to interact with the Dark Side of the Wizarding universe in the parks, and it is almost completely unrepresented... Some people like rooting for the bad guys. Give them their moment, educate the guest it only happens for HHN and make buckets of money. Again. I'm convinced Potter plus both parks is part of the solution for scaling HHN Orlando to a truly worldwide, Vacation worthy Halloween event. And something like Dark Potter is something that would be a 1st in the world of Theme Parks, and could create a new model for in park events. Even if the two could be billed as two separate events, they both share the same ticket. Islands of fear featuring "The Dark Wizarding World" and Halloween Horror Nights.
Also if they could do the above, they'd be able to address how much they undercut the year-round value of their content through the passes they offer during HHN...
