I did the math on this once and it’s just obscene.
For instance a one day ticket to a park costs like $100. Now granted muktidays discount this but for arguments sake let’s say what people pay for snacks and drinks makes up for that. Each park easily pulls in 50k people a day on average. That’s $20,000,000. Each parking lot holds around 10,000 cars and at least gets 3/4 full. $20 per car. That’s roughly 350k to half a mil. There’s the 7.5 million you calculated above. It’s likely that per guest merchandise spending assuming on average every guest gets a T-shirt and maybe a small item is another $50 per guest. That’s another $10,000,000. Say half the guests eat at a sit down restaurant once in the day and pay $30 on average. That’s $3,000,000. Then there’s water parks, alcohol, upcharge experiences, etc.
You’re talking easily $50,000,000 a day in income. And probably higher.
The biggest expense is probably labor. 70,000 employees. Though many of those are part time or seasonal. Say the average pay is $20/hr when you factor management vs front of line. That’s 1.5 million a day. Marketing is huge too - nationwide TV spots can easily be millions of dollars. Electricity, insurance, food, raw materials - all that will cost a lot. Plenty of expenses. But something tells me it’s all adds up to be a lot less than $50,000,000.
Not a math genius here but those at least are some ball park figures.
