All major ski centers are sued constantly, several times each season. (Occasionally, the plaintiffs are right, and the ski center created some kind of additional risk. More often, it's just our natural urge to litigate everything.) As a result, ski centers and patrollers must always have risk management in mind. It's right there along with emergency medicine, rescue, customer service, etc. As a patroller, I can tell you that everything is simple and clean when everyone rides up the lifts; slides down the open terrain; and goes home unhurt at the end of the day. Ski area risk management systems are designed around this model. ANY deviation from this increases risk. I know it sounds boring. Lots of people want hike up; or ride the lift up and then hike outside ski center boundary; or stay on the mountain after sweep and come down later; or any of a variety of other fun, spontaneous, innovative uses of the ski center. All these things sound great, but allowing any of them can, and has, landed ski center managers in court explaining why they didn't stop a plaintiff from engaging in a risky behavior using their facility.
So give 'em a break. Ask for permission, go with what they say, and understand that the employees are trying to do their jobs to the best of their ability.
