My wish list:
- First, tear down the old Mine Cart and TRR.
- Then, I would build GoldRush into a fully immersive experience by merging 3 rides together:
An RMC Hybrid Woody
A Family-Friendly wildmouse (not a spinner)
A Water-Based dark ride similar to the old LooneyTunes or Bermuda Triangle rides at MW/SW.
The RMC would be the showpiece, it could even weave through Buzzsaw, and hug the terrain where TRR was.
The Wildmouse and Water based ride would share the same entrance area - with effectively the same story elements. I would open the ride with a show-style element where miners are led down into the mine. Then I would have a mine collapse element where the only way to escape was to jump in the mine carts, or to try to get out through the underground rivers.
I would even consider building alternate endings to each of the rides, since they're both family friendly you would be able to keep all your stuff with you and wouldn't need to worry about returning to the station. This way you have a reason to ride each one more than once, because the stories will be different each time. The old Titanic attraction at Fox Studios had a similar multiple-ending idea (well, two endings - you got on a life boat or you sank).
I would build both rides around each other with head-chopper elements - potentially even having them interact with the RMC.
If there wasn't the space for all three, I would replace the water ride with a 4D simulator that had the same story with different endings. Lotte World in Korea has 3 different simulators and they're a great break from all the spinning on the other rides.
The Goldrush area of the park would then have 4 rides in total. Ideally I would blend it a bit more with Rocky Hollow/GD to transition from Mining to Bushranger to Corroboree, and have that entire half of the park be 'Australian History' themed.
Down the line, I would update RHLR to have more of a story to it - probably something actually historical like the Eureka Stockade. I strongly believe that having a narrative to work to greatly improves ride theming and concepts. I'd also introduce one or two kid friendly rides to that end of the park, so that parents can do a parent-swap and one of them can keep the kids entertained while the other goes on the rides.
