I'm inclined to think RCI is an addition, if not why wouldn't they have announced a change in World Passport instead of an Enhancement. ....
I'm afraid that "enhancement" is the word companies just about always use when they devalue memberships. For example, Frequent Flyer programs will say they have "enhanced" their program by allowing one to book 361 days out instead of 360, and at the same time will raise the cost of a round-trip ticket to Hawaii from 35,000 miles to 50,000 miles, that sort of thing. RCI has more locations than II and more options for weekend (rather than whole week) bookings, so that could be what DVC means by "enhancement."
I would be GREATLY relieved if DVC were just adding RCI and not dropping II, but if that were the case, there would be no reason to state that trades made by the end of 2008 would still be honored. As for the statement by the Marriott rep that DVC deposits were available through 2011, that
must be a mistake -- Disney doesn't deposit more than 11 months out, and even if they did, II is only accepting deposits through December 1, 2010 right now.
Despite the experience with trying to save the Adventurers' Club, I think it is worth while to call Disney and complain, if one is unhappy with the change. Closing the Adventurers' Club was part of a larger strategy for Downtown Disney, while switching to RCI mostly impacts DVC members. So, if enough DVC members complain, it may have an impact.
I figure I will call my guide -- does any one know who else we could call?
