This review is going to be fairly long to cover all points we wish to make.
We booked direct with Cunard who were then and up to leaving from UK very helpful.
At LAX we were kept waiting for over 90 minutes after going through immigration and collecting our luggage for a coach to take us to our hotel. The Cunard staff did not inform us why until several of us got fed up with waiting and some decided to make their own way to hotel.
