After watching the video on TV, you will report to your muster station. Take your phone (that Has
Disney Cruise Line app loaded). Do not take your life jacket.
At muster station, cast member checks you in. You hold camera up to designated spot near ceiling. And you are done. No standing around, waiting for late arrivals. Very quick and efficient.
The Panama Canal cruise, which sailed a month ago, had a Sail Away Party on pool deck. Looks like they are starting to come back. You will find out when you get onboard.
