Honestly... given that VRTP have moved rides in the past. I actually think VORTEX would be suited more to movie world than sea world. I'd happily see them move it to MW and put a Screaming Swing in at Sea World. However this would only be a good idea if the ride actually ran a decent cycle (which can be done, no idea why Sea World runs it the way it does).
Not sure how Village feels about S+S though, as Batwing actually had a fair few problems when it first opened as well. I'm hoping that they have fixed that relationship as I think a Free Spin could actually go well at Sea World as another thrill coaster to really round out the lineup (1x kiddie coaster, 2x family coasters, 2x major thrill coasters). It also doesn't take up much space which would really suit Sea World. a 2 for one deal maybe?
