I've said similar in this thread and others. However, I think people who buy packages feel that is it s a good value to them either by $ value or just relaxation value as some have mentioned. Either way, that is their choice. I'm one of those Elite penny pinchers who uses OBC to pay gratuities and wifi, and bring on all the water and soda I will drink so I'm not paying onboard prices. It's staggering how much money they make off those packages.
However I see it as a positive for me those that buy the packages, as it's likely to help keep the cruise price somewhat lower to entice more to book, and then upsell the packages. So it's win for me, and the cruise line.
