I cannot see the advantage the DCL has over most of the other cruise companies because there are some great ships out there, that offer much more and charge less for cruises, that don't have the Disney name. Most statements that are derogatory of the other cruise lines are those who have only cruised DCL. Those statements should have the weight of a grain of salt. Many I see seem to make me think they come from immature or bigotted thinking.
I love those that just seem to think they know what they are talking about.
Edd - you need to step away from the Disney Cruise Line boards for awhile! You are taking some people's comments about DCL vs. other cruise lines way too personally. Your arguments aren't going to convince people that cruising with Disney is a waste of money, or that Royal Caribbean's Freedom-class ships are THE best ships out there. Yes, there are a lot of great cruise ships out there, including some older ships (like Monarch of the Seas - 6 years older than the Magic) that don't have the bells and whistles of RCI's newer ships.
I have cruised with Royal Caribbean more than any other cruise line, so I obviously like it. I also like Princess, Holland America, Celebrity, and Disney. Different cruise lines appeal to different people, and there's room for DCL lovers as well as RCI lovers!
