It's a pretty poor situation considering the Merlin parks have already lost a lot of flat rides, that we now have;
Thorpe - Quantum
Chessington - Black Buccaneer
Alton - Enterprise
All either mothballed/not ready to open almost halfway through May.
It’s been more built every time I’ve visited so don’t think it will end up like that - from the looks of it it mostly just needed the theming added now.
I believe they're replacing / upgrading the roof. Something to make it look nicer, easier to clean, etc.
A nice thing to do, yes, but you do have to wonder why this couldn't be done during winter or closed days.
