Of course there are opposing opinions on pretty much everything so there is no right or wrong answer. Just personal likes and dislikes.
I remember once on the mornining of the first full day of our Alaskan cruise, and it was about 7am, there was a woman sitting near me and she was telling her friend how bored she was and that taking an Alaskan cruise was a horrible mistake. I was stunned that anybody would feel that way. But we're all different, right? How she'd decided that after about 14 total hours sailing is beyond me but unless she changed later, that was a lonnnggggggg week
