For those who want a behind the scenes look at the business side of cruise ships and the cruise industry, check out this documentary on CNBC. I saw it awhile ago and gave it 3 thumbs up on my TiVo. It's being rerun 2x on 7/6 and once on 7/11.
I really enjoyed it as well. It looks beautiful in HD. A friend of mine was one of the editors. I hope that they will have it available on DVD someday.
