Not quite. The three buildings right across from the main pool are called "The Springs." One is open now, and last I heard the other two will be opening in May and June.
There are five other buildings currently under construction across the lake from The Springs. Those buildings are considered "The Paddock." Some, if not all of the buildings in The Paddock will be open before the end of 2005.
The buildings you are thinking of will largely be built on the current site of DI's old Fairway Villas. THAT is the construction scheduled for completion in '07. Not sure what official name they might give that part of the resort.
