It certainly is dependent on the access and length of the ride. A tiring day at Universal, Rip Ride Rocket using the single rider queue, therefore those stairs, and with permission, a staff gate, got me to 77 rides.
Stealth is my favourite but though the team tried to count, they lost it and I know that days count won't be beaten. I consider myself lucky if I get a bonus ride. The ride will shut down if the sensors detect weight on the train between offload and load.
I did like Slammer, but a one off and for me, not re-rideable.
