Do they actually do a head count on a muster drill? It seems like there are always stragglers. Carnival certainly does not know specifically that I went to the muster drill. They used to be able to tell that everybody at muster station X was supposed to be there by looking at your life jacket, but now that life jackets are not required to be worn I don't even know if they can tell that.
I don't remember if Princess scanned us in or not. I think they were testing a new system when we were on Ruby last year.
I believe that crew has to do a cabin to cabin sweep, right?
