That's going to be a lot of fun! We are also FL residents and just got back from Disney last week. Before we became FL residents we stayed at the Polynesian which I love, but this time we stayed at the Dolphin. I must say I really like the Dolphin. It's not a Disney hotel but it's considered a deluxe hotel and it's still on Disney property. FL residents also get a special rate, which is nice. I was told the Swan is a little more quiet than the Dolphin. It may be a great place for a anniversary.
You can take a nice stroll on the Boardwalk, take the ferryboat or walk to Epcot/MGM Studios. It's really in a great location!
The Swan and Dolphin also has a few resturants that are quite delicious. I would eat dinner at the Blue Zoo, II Mulino, or Shula's. You also have the Flying Fish at the Boardwalk. If you go to Animal Kingdom catch the bus to the Animal Kingdom Lodge and have lunch or dinner at Sanaa. There's so much to see and do at Disney. Definitely check into a few shows.
