We debarked the Wonder yesterday morning in Vancouver. The Alaskan cruise was our first cruise and seemed very smooth to us. We had felt the movement of the ship but felt no need for Dramamine or any other type of seasick remedy. However, as the day has progressed today all 3 of us have felt VERY tired and felt like the room is moving! What could be going on? Has anyone else ever experienced this? How long could it last?
