The Ride All Day Pass includes admission and unlimited rides and costs $54 ($50 for child or senior).
Any single ride requires a minimum of 4 coupons. You can buy coupons at the CNE Ride Booths in increments of 4 coupons for $5, 22 coupons for $22 or 55 coupons for $55.
During Kid's Toonie Mondays on August 19 & 26, admission will be $2 for kids; the Kiddie Midway (the smaller midway in the north-west part of the Ex, closer to Medieval Times) will then offer 30 coupons for $22 at the Ride Booths. During Youth Day on Tuesday August 27, you will be able to buy 8 rides for $20 at the Ride Booths.
The CNE Zip Line is NOT included with the Ride All Day Pass. This new attraction is $30 for one ride. You get to climb 180 stairs up a 126 foot scaffolding and ride along a 1,100 foot-long zip line (which takes approx. 30 seconds).
Buy your ticket online for an additional $2 fee and you'll get a specific time slot. When I attended the media day, all Zip Line riders (not me, because I'm an out-of-the-closet chicken) were set with a Go Pro camera on their helmet and were told that for an additional $10, they could get the clip filmed during their ride.
