Same at Whistler B.C., and, from the YouTubes, at the La Paz, Bolivia, Mi Teleferico system. At La Paz, the doors open when the cabin reaches the unload platform, and remain open around the turn until it reaches the end of the the load platform. Passengers are blocked from exiting while the cabin rounds the turn at higher speed only by portable ropes placed along the platform edge. It will be interesting to see whether Disney thinks that's adequate, or they close and reopen the doors for the turn.
But Rob says he sees the cabins stopping inside the station. I believe he is mistaken, fooled by the distance and angle at which he is viewing it.
I agree, I think they are slowing but not coming to a complete stop.
