Haven't been on here for a while so forgive me if I repeat myself.
Our best operator runs the line at Swifty like an MP directing traffic. Short, crisp directions telling who to move and where to move to. Not just "you two are next" but "you two take the middle seats, red jacket join from the left, green jacket join for the right" "GO-Go-Go" "Green jacket either get on the chair or get out of the way, PLEASE" Very few empty seats when he's on duty.
On Ramcharger there is still a lot of confusion. Groups of 4 or 5 will not willingly split up or move in to fill the empty 3-4 seats. They also block singles and doubles from access to those slots.
Having skied each chair hundreds of times, the biggest issue is guests not being ready to or able to move out when it's their turn. Not as much of a problem on Powderseeker because those folks can ski, plus the locals will push their way to the front when they see an empty slot.
