Samantha:
Thanks for coming to the Mom's Panel for our help!
I can see where the confusion comes: the answer to "Who can register?" under the Honeymoon Registry FAQ only states "guests of select Disney hotels"....I couldn't find a specific list.
However, because you have to give your confirmation number for your honeymoon vacation at Disney when you create the registry, you'll only have one by booking a Disney hotel that is available under Accommodations on its registry . As you know, the Swan & Dolphin, although located on Disney property, are actually run by the Starwood family of hotels, and Disney does not handle those reservations.
I wish I could "shower" you with the good news that you could register, but it looks like
Disney's Honeymoon Registry is one of the perks of guests who choose a honeymoon at one of Disney's resort hotels--and a few non-Orlando destinations like Vero Beach! If I were in your shoes, I'd weigh the savings of your employee discount with the possibility of the registry helping offset your expenses by providing friends and family an easy way to help make this time special--and affordable--for you and your future husband.
Wishing you a magical honeymoon!
