I would investigate the following:
CBR - 5th sleeper room
POR - 5th sleeper room (as PP noted, for CBR or POR 5th sleeper, the murphy bed is small and really for a child, so may not work for your party)
Ft. W cabin - 1 queen, 1 bunk bed, 1 sleeper sofa
WL - a CL Deluxe room (2 queens and 1 sofa bed) or a room with bunk beds (you have to book a "bunk bed" category to guarantee you get them)
AKL - room with bunk beds (again, have to specifically book a bunk bed room)
BWI - Deluxe CL
BC - Deluxe
CSR - various suites (junior, executive, etc.)
GF, CR or Poly will guarantee you 2 queens and a day bed
AKV - 1-bedroom
BLT - 1 bedroom
BCV - studio
BWV - studio
BRV - studio
OKW - 1-bedroom
Poly Villas - studio
VGF - studio or 1-bedroom
You could also do a 2-bedroom villa or 2 bedroom suite at any deluxe or deluxe villa resort.
Personally, for comfort, I would probably opt for GF, CR or Poly (resort, not villa) to guarantee 2 queen beds and a day bed. I find the day beds in those resorts to be much more comfortable than any of the pullouts offered in the mods and villas. Or, if you are willing to splurge, book a "dedicated" 2-bedroom villa to get 1 king, 2 queens, a living room, kitchen and washer/dryer. We've done dedicated 2-bedrooms (paying cash through WDW) at VGF, CCV and BC and they were fantastic.
