I find it hard to quantify because if you're having a bad day then it can't always be 100% justified, but forgoing the emotional element, lets make a little matrix to determine the expectation of a park day that's somewhat just based in logic. First, let's map out the attractions.
There's must do attractions that drag people into the park. They're the sort that you get really excited about and seek the park out just for them such as:
Wild West Falls
Super Man Escape
DC Rivals
Then there are the attractions that are good fun whilst you're there, but not exactly show stoppers:
Green Lantern
Scooby Doo Spooky Coaster
Justice League
Road Runner
Batwing
Depending on whether you've seen it or are interested in it, this may also fall under good fun:
Hollywood Stunt Driver
And then there's the rest. This would change person-to-person and group-to-group, but above is how I see it.
Now we can do some 🌟M A T H S 🌟
Let's give the park an attraction score. To do this we map out the attractions and give them a number. Must do's are 3, Good Fun's are 2, and the rest are 1s.
With my quick math's I got an overall attraction score of 32. I know that seems low against the Movie World website but I've excluded any upcharges, land mentions, and I've marked all assorted main street shows and meet & greets as 1 point each.
From let's try figure out the 'expectation' for the days quality which we can do by dividing the park attraction score by 5. When rounded out this gives us a 6.
Now, using today as an example, let's add up the attractions which are currently down using the same numbers we gave them above which we will call the 'outage score'. This is what is down today:
Wild West Falls
Superman Escape
Batwing
This gives us an 'outage score' of 8 against an 'expectation' of 6. Now it gets a bit subjective, but the distance from the 'expectation' should be a good determination of the day with the score itself being 'average', so today would be below average.
The reason I've mapped it out like this is because (I hope) that it can easily be applied to all other parks and creates an equal footing for the expectations of parks and future planning. For example, after the April school holidays the park is going to have a scheduled 'outage score' of 9. If anything goes down, especially any other 'must do', then it's going to create some really lackluster days at the park.
I'm open to criticism against this or suggestions on how it can be improved as I know it's not perfect, but I try to keep things as objective as possible when figuring these things out. We've got a lot of stuff like this that factors into our review scores as well because whilst emotions are important, they can't always be trusted to provide valid recommendations and insights.
