I'm pretty sure a small flat ride could fit there... Storm Force fits between Hulk and Doom. Universal could also build it slightly into the lagoon like they did with Hulk. I agree that a Skipper Tours station probably wouldn't fit. Popeye could be hidden in some way and backstage space could be covered or themed.
But why does the lagoon need to be hidden? The whole idea is that you're on an ISLAND... when I'm at a lagoon, I expect to see an ocean lol.
Either way I think Toon Lagoon could use a few family rides (no height requirement) somewhere. I'd love to see little kids enjoy every area of the park, not just Seuss.
@darkridelover - Yeah, that probably is a little too pricy... so $150-175 million for a whole renovation? Didn't realize HP 1.0 only cost Uni $265 million! I'm glad I'm not running the $1.5 billion expansion! Maybe they're packing a lot more into their long-term plan than I thought...
