So, only DCL passengers were not complying? No issues with other cruise lines? Nah, not buying it.Simple, the passengers.
I cant remember the exact report, but the reason Disney switched back to the in person Muster was because of the large % of non compliance of passengers doing the E Muster on embarkation day. The Muster is a legal requirement and the coastguards reports showed that too many people were not doing the E Muster. So Disney had no choice, they had to switch back to in person Muster, to make sure they hit the legal requirement.
