As for the seas being rough, it was a little rough leaving the Heads from Sydney (which is normal). Going to Hobart most people were asleep so they were fine but it was rough. We were awake and it was quite rocky between 2am and 4:30am when we eventually went to sleep. The final sea day leaving Hobart was extremely rough. Around half the guests were sick, people were stuck in their cabins, you couldn't walk a straight line, they were handing out sick bags at Cabanas and they were in the bathrooms as well. Medical Bay was full and we heard from lots of people that they went to get the sea sickness shot. It was rough all day, worse in the morning between 7am and 2pm, was better after that but still quite rough. Pools were closed all day, Deck 4 was closed as well. It was too dangerous. Waves came up and hit the windows on Deck 3, waves smashed 2 windows on deck 2 as well. It was rough and not that unusual for that area.
