BTW, given a week's reflection after a cruise on the Dream, the irony of all this MM+ is that DCL truly is a textbook example of "Blue Ocean theory." 14 years ago, the main DCL demographics--families with kids under 12 and Disney-fanatics--simply didn't cruise in meaningful numbers. A few here and there, but most cruises were for old people (Princess, Holland), or singles looking to drink and mingle, and maybe sample the flora in Jamaica (Carnival). All ships had casinos, you had to wear a jacket and tie to eat in the main dining room that looked like the Grand Hotel ca. 1960 (even on the "fun" ship), the only non-staid thing about the pool was the topless deck up above it ...
DCL changed the industry. Most notably Royal Caribbean has followed suit but Carnival too has been forced to adopt a lot of the Disney model. Ships are now routinely full with guests who previously would never have considered cruising. Rather than compete with Holland/Princess/Carnival, DCL effectively created a new industry and made others compete with them.
So, of course, in an attempt to make a "blue ocean theme park," TWDC ignored every lesson that could be gleamed from DCL. The things that set DCL apart, from other cruise lines and from theme parks, are put aside for a convoluted retread of the failed FP system and IASW dolls that say your name creepily.
