I'd agree with this - for the first time we've got really interesting stuff happening all over the country which is historically unprecedented, it's a really good time to be an Aussie enthusiast for sure.
I'm sure management have got plenty of ideas that weren't in the announcement, and that still doesn't change the fundamental reality that when these projects are done, we'll still have the same haphazard Dreamworld master-planning that's been at play for the last two decades. This isn't about creating some unrealistic Disney-level of park because right now even industry substitutes (casinos, shopping centres, smaller play centres, local council parks etc.) are nipping at Dreamworld's feet in regards to immersion, and so the bar of "she'll be right, they're trying as hard as they can, give 'em a break" is not conducive to Dreamworld actually being profitable in the long term. Simply put - I don't think I'm being unreasonable in expecting Dreamworld to be more considered in their master-planning - if they can do it for Tiger Island (which is easily one of the best themed areas in the country) and if they could do it in the 80's, and if their competitors can do it, they can too.
Speaking of the 80's, you're right, John's park is long dead and that horse continues to be beaten. For me I acknowledged that when they got rid of the facades for Sky Voyager John's park died (and died again when they knocked over Hollywood Cottage for Steel Taipan) - realistically if any management doesn't understand the significance or doesn't ask why the way things are before gutting them, then the hope for clinging to any other aspect of John's original park and what made it so great compared to now should be well and truly abandoned. And yet, the double-speak is at play, because the whole reason it's called Rivertown is because of its adjacency to the Murrissippi River. Both it and Rivertown are nods to John's Dreamworld. So which is it? We want to acknowledge the history and heritage whilst simultaneously not respecting it?
I'll try and speak to this briefly because I acknowledge this isn't everyone's cup of tea. But, the tricky thing with theme park leadership is that unlike other businesses, any capital expenditure decisions, even at the sub-million mark, are going to have wild impact on other projects/amenities/facilities/attractions/etc. for two to three decades. So if you're not insanely considered in thinking about how your decision is going to look in three decades' time in the most holistic way possible, it's super easy to end up having V8 Redline in Ocean Parade, or worse yet Troll's, especially when there's a mountain of other stakeholders involved who don't respect or get how theme parks (and theme park design and its impact on revenue) work. Worse yet, if those stakeholders don't understand the rationale behind retheming something for the sake of it, why would any board approve major capex spend when it doesn't move the needle during a time when the business is still skating on thin ice? By extension, if you can't roll in a few million to include the park's most popular ride into the new precinct that's happening metres away, will it ever happen? I could go on about this forever but it'd probably bore 99% of enthusiasts here because it's not about the fun stuff we all enjoy talking about - point is, measure twice cut once, and I don't personally see a lot of that in some of these new announcements.
