Yeah in retrospect you are probably right. I think Australia can handle another Flying theatre attraction but probaly not another on the Gold Coast. Lets substitute that for a heavily themed Vekoma Mad House inside the castle. Something unique and would be a great family attraction.
The Halfpipe at LPS - yeah I chose that more for the available room and that could actually fit in the space presented in the above plan. Maybe we could stretch the Intamin relationship even further for LPS with a clone of Sandy's Blasting Bronco. I am rather attached to bringing a dark ride back to LPS and have it well themed to a Ghost train style atttraction. I know that might be a little controversial for some but it would be a great nod to the past and I know that there was serious thought in bring a Ghost train style attraction back to LPS previously.
Nah the Galaxi is old hat. As are the other old flats. Enterprise is due for replacement Twin Dragon and Pharoah's Curse are both junk to be honest. Better off without them. The Spider I would entertain in keeping as it certainly has some historical value. Really though, some modern versions of these rides would be better for LPM moving forward. Older rides are harder to maintain, harder to find parts and more expensive to run. Given that they have the Scenic Railway and Carousel as already vintage and costly and VERY maintainence heavy rides, a roster of new ,reliable rides would do wonders for LPM. I would however, redo all the effects in the Ghost Train- make them much more effective with new lighting, sound and jumpscares with lots of blasts of air whilst still retaining the charm of the original ride.
