Loving the Donkey Kong style coaster for Roadrunner. It makes perfect thematic sense. Only problem is I want to connect it all to the actual Looney Tunes area and there's only space if we combine the walruses and ski stadium for either a dark ride or coaster, not both. I think our best bet is to do the Roadrunner Express as a highly themed family coaster for the Seaport expansion, and then do a more thrill orientated coaster to replace the Vekoma SLC. Perhaps the more thrill based coaster could tie in with dinosaurs? We could basically have a dinosaur mini land with the SLC footprint, the 3D cinema (which debuted with Dinosphere which we could easily update) and then ending with the dinosaur overlay of White Water Safari. That lines up with the geography of the park as it is. Hmm...what if we did an RMC T-Rex and called it...get this...T-Rex!
I wouldn't worry too much about ripping off Great America because the parks are already in a huge competition with each other so Great America getting a Raptor and then Discovery Kingdom 1-upping them with a T-Rex is actually perfectly in line with the current rivalry narrative between the two parks.
