We missed the muster drill on EOS last Jan. because we were at the check-in counter. We were told to read the instructions in the cabin. I did make it a point to locate our life jackets and find our muster point in case of emergency. I didn't worry about it and was actually glad we didn't have to do it because we were stressed out and exhausted with the trip to get there due to airline delays and missing luggage. At 5:00 we made it to our cabin and collapsed on the bed, fell asleep and missed the sail-away.
