Serious concern about safety training of crew..

     We have traveled with Norwegian Cruise Lines many times and have had a great time each time.  That's why we booked this trip.  This ship is just too big and crowded.  It has the normal amount of public space but with more people, far too many people with far too little public space.  My wife is in a wheelchair and trying to navigate through the corridors and most other spaces was also an issue.  It was too tight for a wheelchair EVERYWHERE!  We couldn’t even fit the wheelchair in the cabin door without folding it first.   We usually find a quiet outdoor space to enjoy but we were unable to find any quiet outdoor space to sit away from crowds and screaming, misbehaving children. 

     When it was time to disembark in Miami we tried to exit the ship on deck 7 near theater as instructed by the constant announcements. It was total chaos!!!   The crew had stopped the exit line as we were about to exit and placed a rope across it.  We spent  the next 1 1/2 hour standing packed like a sardine, unable to move. (all elevators open and packed) It was hot, nobody could move, claustrophobic, babies screaming because of the conditions.  Others, like us, also trapped with wheelchairs and luggage. We could not even turn to exit another way!  The crowd took a small child and passed him over the rope so he could catch his breath.  When the child's mother tried to exit to get to the child, she was stopped and told she could not exit!!!! We were screaming for help with an occasional crew member coming to the rope.  ABSOLUTELY NO CREW came to direct or help.  We were packed in so tightly that someone broke my glasses while I was wearing them.  I finally managed to get my cell phone from my pocket and had to call 911..... The crew only came when a medical emergency developed and people started screaming for help.  If this is how the crew handles a crisis, I am very concerned about what would happen in a real emergency.  I strongly recommend that they look at better crisis training for crew on this ship.  This is just UNACCEPTABLE!!!!  We will never take the Norwegian Getaway again!!!
