I have the Efteling as a work in progress. Started over a year ago. But only bult a quarter and then I got a bit bored with recreating other stuff instead of building my own.
Besides that, the fairytale forest I build has already thousands of pieces.

if you are interested. I've added all rides and updated the workshop save this year sometimes, but it's nowhere near completion.
I didn't specifically mean recreating the park, but rather using the Toolkit to create Efteling building sets and props, and perhaps "fake" rides that don't work (yet) in the game, like the Pagode.
I've concluded that Planet Coaster, or any game, just isn't enough for what I wanted to do with my own park; that and the fact that it's too difficult for me to still have fun while building anything else with the limited amount of time I have. Instead, I plan on just going straight for a bare game engine (Unreal) and start building a virtual ride (which will probably at first be a recreation of one or two Efteling rides to get a feel of how I could do it).
I still intend to create original building sets and props for the game for others to enjoy, perhaps by combining it with my own virtual park.
