The only time I can think of is when I went to SFGAd. I rode Batman & Robin: The Chiller (Robin Side) 23 times within 2 hours. This was when it still had over the shoulder restraints and nobody was riding it, so I just stayed on. I didn't even get a headache!
This year during gold pass twilight rides on SOB I got about 15 without getting off the train. There was snow on the ground and it was about 30 degrees. I can't believe I did it now but that coaster runs a lot better when its cold outside. I can remember that it was me in the back seat of the train and then 6 people filling the first car. I was getting wipped around back there.
