No, there is no "special WDW frank". You will get a Lake Buena Vista frank and thats as exciting as it gets! Sometimes if you order something from Disney (tickets, photos etc), they have their own franking machine and you will get something more "Disney" on it, but for your own postcards, it just the stamp from the local PO. There is small section on this in most of the WDW guide books as there have been quite a few queries about a WDW frank. Sorry! The Virgin person probably gets a lot of mail direct from WDW which has the Disney frank on, which was confusing her.
