My pick would probably Grand National at Blackpool, I could see why people like it, but it bruised me up way too much for me to ever want to ride it anytime soon.
I must say, Manta at SWSD is surprisingly forceful, i enjoyed it a lot more than its Orlando sibling
I'm not sure if people just don't know much about it, but Wicked at Lagoon has some amazing airtime on the top hat/hill
For the Gentle Giants Petting Zoo, maybe a family coaster that rides on the back of the dinosaurs with long necks would fit? Also, for either the Mosasaur Cove or the Stegosaurus area, a jaws-style ride might work with either a giant crocodile or something like that
Exited to see how this turns out!
Since nobody else has brought this up (i think), if found this bit of info on Wanda's website
theres also this image for the park
^ looks like a wingrider ?
