Maybe I am reading it wrong but it appears renting the
Disney Cruise using points is prohibited under the Membership Extras Acknowledgment and Disclosure Statement, which you can find online at the member site by going to "MY
DVC Membership" -- "Important Membership Documents" -- "Access to Membership Extras." The Disney Cruise and other Disney Collections are incidental benefits, which cannot be assigned or transferred, and although the Cruise and other Disney Collections can be used by "Members or their guests," they are for personal use only and cannot be "rented."
