I'm throwing together a last minute trip for 09/19-09/23, and both the Swan and Dolphin have availablity for my dates.. I've never stayed at either before. Is one better than another? Which is closer to the boat dock? I've stayed at BWI before, so I'm familiar with the Epcot resort area, just not the Swolphin. :> Any advice you can give me would be greatly appreciated.
