As far as exhibitions go, I believe the CNE is one of the more venerable - it's been around since 1879 and attracts over 1.3 million visitors every year.
Looking at the website before I went, I saw that they had a nice summary of all the ride height requirements and number of tickets required. I thought perhaps the data could stand to be presented in a more visual form.
First, how about the number of tickets required for the different midways? All of the rides on the 'Kiddie' Midway require four tickets, except for one (The Wacky Worm Coaster). The Adult Midway rides are split about 50/50 for five or six tickets, except for one (Sky Ride) which only requires four.
With tickets being $1.50 each, or $1 if you buy them in sets of 22 or 55, that makes the ride price range $6-9 or $4-6. Assuming you buy the $1 tickets, the average price of an adult ride is $5.42 and the average price of a child ride $4.04.
The rides also have height requirements. Note that I've simplified things by taking the max height for cases where shorter/younger kids can ride supervised with an adult. Here's a breakdown of the percentage of the rides in each midway type children can ride, given their height:
|Google Docs does not allow non-stacked stepped area charts, so line graph it is.|
And here's the same breakdown with percentage of the total rides (both midways combined), coloured by type. This is a better way to represent the information, as it shows the discrete nature of the height requirement:
Basically if your child is over 4' they are good for about 80% of all the rides at the CNE.
Something else to consider - how to get your maximum value for your tickets with none left over, given that they are sold in packs of 22 and 55? I would say go with the $36 all-you-can-ride option. Also, how miniscule are your actual odds of winning those carnival games? Because I want a giant purple plush gorilla.
See you next year!
