We're going to the future, and by that I mean 20 years into the past.
The amount of work put into that future city that probably never gets utilized by anyone, is immense. There's plenty of open space around the park, so prebuilts will slot in nicely if you don't want to bother making custom coaster. I'll build more custom coasters later for the more complex, non flat maps, but you really don't need to use that much space for this scenario as you can see by the thumbnail.
By all means, copy the wooden prebuilt. I copied it myself from Marcel, I think(A lot of these prebuilts are just kind of leftover from the last times I played this. I have no idea where they're from besides the single corkscrew only design from Marcel). It's got awesome throughput and brings in the crowds AND the bag.
Feel free to support the devs for amazing QoL/continued support for a 20+ year old game that formed a core memory for many people's childhoods. Chris Sawyer, you're awesome for making this game, and the OpenRCT2 team is awesome for modernizing it.
