They did impact.
It might have been both.
It should be pointed out firstly that VRTP are in a unique position - the VRTP Oxenford property was a Commonwealth Games venue and given the lack of car parking at the Studios (because it rarely needs it), it's fair enough that people may have been put off going to the theme parks at the Oxenford property out of a fear of not finding a car parking spot due to Commonwealth Games visitors possibly parking at the theme parks instead. Hence why VRTP took precautions. However, in the end, finding a car parking spot at the Oxenford theme parks during the Games was likely possible due to locals leaving the region for the Games duration.
VRTP (including SW) average attendance is 7000/day while Commonwealth Games is about 100,000/day. 22% (or 22,000 visitors/day) of Commonwealth Games average daily visitation & I believe 60% (or 4000/day) of average daily VRTP visitation is likely from the immediate Gold Coast-Tweed Heads region.
No doubt if it was the latter 'choice of words', 65% of VRTP visitation by locals would have disappeared (so reducing it to 1400 locals/day & 4400 visitors/day). Adding the earlier 'choice of words', it should have resulted in nearly no one going to the theme parks but if the 65% of the population who left the region for the past few weeks stayed instead, visitation should have declined to about 4250 visitors/day.
Basing it on the above 3 possibilities, the 1st possibility is the most likeliest - that is, because 65% of the Gold Coast-Tweed Heads region's population left for the Games duration (the latter 'choice of words'). The other 2 can be ruled out because locals did leave the region in the last few weeks and it's highly unlikely all VRTP parks would have been near-empty. Being tourist attractions, they would have been a reasonable amount of visitation (mostly from non-locals) to remain open even if it was less visitation. Otherwise, it would have been better to close for 2 weeks to save on operational costs.
I haven't been following their pricing strategy closely but is the recently launched discounts you're referring to that 1 Groupon deal? 1 discount doesn't sound like much to say they got their strategy wrong.
Currently, the future of Gold Coast theme parks are in Gold Coast residents' hands - do they want cheaper tickets resulting in likely lower quality parks or more expensive tickets resulting in higher quality parks? Just don't take the parks for granted. The best outcome from this new pricing strategy is if it brings in more customers, resulting in lower in-park costs (such as upcharges & food and beverage). However, this is unlikely. The chances of success would improve if they did solid marketing towards non-local audiences however in the current economic environment, it would be difficult to achieve a success in this. Hopefully, they could at least try to do some proper non-local marketing to test the waters (It's been a while since they've done any significant non-local marketing).
DC Rivals HyperCoaster would've been the perfect opportunity to return to targeting these markets but based on how much marketing I've seen (none), that opportunity has well and truly past (at least for interstate visitation). What better way to encourage non-local visitation than promoting the Southern Hemisphere's only hypercoaster? And I doubt the Commonwealth Games will help significantly particularly since they didn't do non-local marketing in the past couple of weeks.
It's not a guarantee that they will lose heaps of revenue. The next best outcome is if Gold Coast residents don't take the parks for granted and accept the new pricing strategy. If they in general can't afford it, fair enough but if they take the parks for granted, the parks quality will lower to their detriment. Accepting the new pricing strategy will allow the parks to gain more overall revenue to spend on improving the parks including adding more frequently higher quality attractions & possibly lowering in-park costs.
All other possible outcomes would mean in-park costs would increase due to less attendance. Less attendance would mean, instead of expansion, more older attractions being replaced to ensure capacity adequately meets attendance. However, expansion could be an option if they can successfully increase attendance from an increase in non-local visitation & new higher quality attractions could be added more frequently if they gain higher overall revenue.
The worst case scenario is if they get both less renewals & less revenue as that would mean they would lose more overall revenue, which would pretty much mean a return to discounting resulting in new attractions being built less frequently or if frequently, lower in quality. Otherwise, in the far future, the parks might as well have a 'free entry, pay per ride etc' pricing strategy instead and that would mark an interesting milestone in the history of Gold Coast theme parks. The outcome of this change in pricing strategy & the parks' reaction to that outcome could be the turning point in Gold Coast theme park operations.
