Well, DUH, it's Disney World! The Swan and Dolphin have a boat launch that goes directly to the front entrance of Hollywood Studios and the back entrance of Epcot! The other two parks can be reached by bus. (The Epcot entrance is the back entrance so you can walk right into Paris and the Ratatouille ride!) The Boardwalk has carnival games and shops as well as a few amazing restaurants including the new Cake Bake Shop which is NOT to be missed! And there are pizza stands and corn dogs and the Atlantic Dance Hall which is open late so don't be surprised if you see a man in a tux carrying a woman in a white dress over there after the reception for a little after party! If you do see that, follow that bride!
OH! And HOT TIP! The Swan and Dolphin (and Swan Reserve) are all Marriott properties so you can use those Bonvoy points AND still get all the perks of staying on Disney property like extra magic hours and free and easy park transportation!
