The number of passengers depends on many factors.  Wind dictates most of the variables related to number of guests and tethered balloon height.  Wind, Size of the Hot Air Balloon, Height of the ride, Size of the Area, Length of Ride and size of the passengers all factor into balloon tether feasibility.  On the average we fly the hot air balloon ride up to the top of the ropes and back down, averaging 5 minute duration/intervals.  Ideally we process  12-15 trips in one hour.
