Last night the wave starts to rolling. We went to hide and see wave pounding the window. The whole night we can feel the ship rock left and right . This am I go to have my coffee, due to strong wave, it knocks down plate, coffee pot and staff says it is the worst they have experience. I feel very bad for the server, they still have to clean, cook and serve. Head up to them and greatly appreciate all their hard work. The excursion on land will be sightseeing. Additional tours is expensive to start from 249. We decide to do the free tour. Overall it is wonderful tour and see so many wildlife. Especially the orcas attacked the humpback whale calf and group kill. The biologist on board say it is once in life time to observe the event even it is sad.
