My view is that Disney have been watching the success of SW's Discovery Cove with great interest (and jealousy!), and are working on ways of doing something similar, and the Destination Disney is part of that process. They have worked out (slowly) that there are a significant number of people who are willing to pay top dollar for an element of exclusivity with their park visits, and this is largely pandering to that wallet range. IMHO, it doesn't (or at least it shouldn't) impinge on other guests' enjoyment of the parks and is simply an (expensive) optional extra, rather like the behind-the-scenes tours. If this experiment is successful, it should add a sigificant amount of revenue to the parks, which can only be good for the overall experience.
