Scream Machine I've ridden many times in a row
Nitro I could ride for a whole month...
When Bizarro was Medusa and no one would ride it I actually went on it for about 3 hours straight, without getting off...(I actually was asleep for atlest two rides)

Breaks
Yes would think so - events like this always have a break every few hours
