None of the Disney owned resorts appear in either Hotwire or PL. Swan/Dolphin doesn't come up very often. If you want S/D betterbidding will tell you the EXACT amenities to look for on Hotwire BUT getting an Entertainment, occupational or AP rate from S/D is the best way to get the S/D at a discount.
You shouldn't have any problems getting 2 beds (in Orlando) BUT there is no guarantee. There have been people who were stuck with a King bed, handicap accessable room. Keep in mind you are only guaranteed a room that can sleep 2.
