I booked one 2 Queen and 1 King (2 rooms) and a parlor.
https://swandolphin.com has information about the suites but is not comprehensive. I believe most parlors (if not all) connect to a King and a 2 Queen room, so you can definitely book a room with 2 Queens and a parlor, or a King and a parlor. I'm just not sure if any of the suites connect to 2 double rooms or 2 King rooms.
Someone earlier was posting about the Governor's and Presidential suites, but I was told those were reserved for conventions (I tried!). Not sure if there is really much difference at the Swan between the grand Suite and the Executive suite (besides being slightly bigger)
