Alex B - it's also dismaying to note your ignorance of Dreamworld's capital acquisition process. The decision to purchase a new ride does not come down to "a 55 year old engineer." The decision to purchase a new ride is an incredibly long, complex and drawn out processs. It involves many, many people at various levels of seniority within Dreamworld and Macquarie Leisure. Furthermore, the decision is primarily market driven towards meeting the needs / expectations of the very demographic you describe (ie, 7-40 years). A purely personal preference of one person plays no part in such a multi-million dollar decision.
Sorry if I seem abrupt - I just can't let such inaccuracies fester on this thread.
