The last chance to exit is when everyone goes to their pods to be seated on the ride. I am pregant so I couldn't ride on our trip last week, but I went all the way to the boarding area with my mom and fiancé who both rode (though my mom definitely wished she hadn't after the 1st 10 seconds because she got so sick, she was actually sick for hours afterward). It was neat to see the ride, then you walk down an incredibly long hallway to the exit, where they have interactive games and make your own postcard stands.
