Hello, Patrick!
I like how you think!
While I don't know of any Fantasyland-themed Disney Vacation Club properties, I can tell you that the addition of DVC villas at Disney's Grand Floridian Resort & Spa will add to the number of DVC villas that are within a quick monorail ride of Fantasyland! That, to me, is truly the ROYAL treatment! (Can you tell that I can't wait to try out these villas?)
Beyond that, don't forget that Disney's Port Orleans Resort-Riverside has recently added the Royal Guest Rooms, which "place your family in the middle of some of your favorite Disney stories."
These Disney Story Rooms really add a royal touch to the decor, with some classic Disney magic lighting up each room, as well. Disney Vacation Club Members are welcome to use their Membership to book lodging at all of the Walt Disney World resorts, too!
Of course, we never know what those crafty Imagineers have up their sleeves, so anything is possible with faith, trust and pixie dust! Until then, consider what they've cooked up thus far. I know I'm ready to explore them both!
Please send whatever additional questions you may have as you think of them! I'd love to help!
