This was my wife's first cruise, so to say the least, she was nervous and anxious. She has a fear of deep water and being out of the sight of land. It was a little rough the first day with twenty foot swells and of course, lots of walking. She has been experiencing knee pain in her left leg so mornings were find but by the late afternoon it was getting to the point of unbearable.
It was not as bad as she thought it would be, the walking did her in more than the fear of not seeing land.
