Steve,
Call now with your SPG number now and make any request that you may have. You do have to ask for a possible complimentary upgrade/view, etc. They will not automaticly offer them, so ask politely. The Jr. Suite is 2 rooms with a connecting door, with a queen murphy bed, queen sofa bed and a king bed. Each room has 2 full bathrooms. The Jr. suites at the Dolphin are very roomy and I think you will be comfy for 12 days with your family. You will love the beach theme, the grotto pool, the piano player in the lobby and access to Epcot, MGM and Boardwalk. Happy planning!
