At the end of the tour each SUB will be clipped back onto the docking line. Units will then be brought back up to the boat one by one, just as you descended.

You will not need to equalize your ears to exit the SUB.

You exit your SUB with your bottom first (sliding back off the seat) and then ducking your head out of the bubble. Push away to the ladder along the sides of the SUB. It's the exact opposite the way your entered!
