DVC wouldn't disappoint you by holding back such valuable information. The themes have been on dvcmember.com for six months, since February, when the third edition of Cruise News was sent out. It's under the section header entitled "A Wonder-ful Itinerary" and the third edition of Cruise News is below that. Then again, with nearly 10,000 postings on this thread alone, you might have to rely on dvcmember.com for a more streamlined look at what's being planned. Thankfully, DVC isn't requiring us to wear B&W things, Pirate stuff, or our Royal Finest... it's just a recommendation.
No matter what we wear, I'm confident that we'll have a great time. I have it on very good authority.
