I don't think we have a topic (I searched) for this park yet, and we're gonna need one...
Why? Because it's getting a wooden coaster next year, is generally fab, and is only 45 minutes away from Calais!
I visited yesterday and was lucky enough to get to chat to two management staff and try and coax SOME information about the planned wooden coaster for next year... Unfortunately we couldn't, but found out some interesting information about the park and the Plopsa brand (they own 5 parks, including Holiday Park) in general...
As for this year, they're theming up their Teacups to a new IP of their own (Studio 100 own the Plopsa parks, so they are filled with their own IPs), called Princessia, which involves a 25m tall castle, a new restaurant and some sets... Once they get permission to build, they'll put planning in for the coaster...
Here's some concept art:
