Are you looking for a package that includes the wedding/ceremony itself or are you just looking for a vacation/honeymoon package for Disney World?
To have a wedding/ceremony on Disney property, you have to go through Disney's Fairy Tale Wedding department (
LINK). There are basically three packages through them: Escape, Wishes, and Couture.
You can also have weddings at the Swan/Dolphin or several other places around Disney (Leu Gardens, Cypress Gardens, and more).
Disney does offer some honeymoon packages (see info at the link above), but to be honest, I think I'd try to book all of that kind of stuff myself without going through Disney. It would save you lots of money! Use
AAA or any other discounts you can find to book your resort and get tickets and book any special events you want to do (tours, fireworks cruises, etc). You can make reservations for any of the restaurants (and tell them it's a special event!) and you can make your wedding/honeymoon as romantic and fun as you want it to be.
