Chessington World of Adventures holding public consultation regarding “current proposals and new developments” - potential new attraction?

[Peet]

It looks like literally the whole park is greenbelt:




Based on what's going on near where I live, greenbelt land doesn't really mean anything, you can just declare that it's actually "greybelt" and build on it anyway .
I guess the park has agreements with the council about what can be built where.
