I was on the boat for this crossing and have to say that I didn't think it was too bad.
My wife, 6 year old daughter and 20 month old child would beg to differ though.
I felt the staff were excellent at looking after the passengers. We always sit upstairs in the Niarbyl lounge and every 10 to 15 minutes members of staff would walk around asking if everyone was OK. Cleaners were constantly on the look out for any "expulsions", including checking the toilets and at one point I asked a member of staff if my family could have blankets as they were getting cold. These were quickly brought to us. Bottles of water were handed round by the staff and the first officer kept everyone informed at all times.
I think the SPC staff made an unpleasant crossing far more bearable.
Thank You
