We just got back, and we had to report to our muster station any time before the Ship sailed. We arrived at said muster station at which time our "Sail & Sign" card (also used for cabin key) was scanned. At that time the crew member showed us the proper way to put the life jacket on, and explained what we had to do in case of the sounding of the alarm. Lasted about 5 minutes, and we were done and on our way. We weren't instructed to watch any video on the cabin TV.
