Not to complicate things further, but have you considered renting DVC points for a room that could accommodate your group? (Some, not all, of the DVC studios accommodate 5 adults - the pull down bed is fairly new to some of the Deluxe villas.)
I checked multiple scenarios for the same one night in October - if you could rent points, using one of the online brokers (you tell them what you want and they arrange everything for you - there are calculators posted online so you can see the cost), a studio at a Boardwalk Villa is $150 for a night to rent points versus $219 + 12.5% tax = $246.37 a night for a room at POR through Disney. The Boardwalk studios are almost 100 sf larger, and the new pull down bed is longer than at POR. Wilderness Lodge Studio Villa or a Beach Club studio Villa is a bit more at $225 a night to rent points. All a lot less than $384 a night in the Finding Nemo Suites. If you rent points you won't have the extra bathroom, but you will have more room during the day (fold up couch/murphy bed), a microwave and fridge. Make sure you confirm with everyone that the villa you choose sleeps 5 - Disney has just redone some of the deluxe villas, and previously the studios slept 4, but there is not info out there that the pull down murphy bed allows sleeping of 5.
AoA Nemo Suite: 520 sf $432 a night (including tax) $2,274.76 for 11th-16th
POR through Disney: 314 sf $246.37 a night (including tax) (I didn't see any rooms available for the full duration of your trip at French Quarter.)
Boardwalk Villa Studio: 412 sf $150 a night $870 for 11th - 16th
Wilderness Lodge Studio:356 sf $150 a night $1,155 for 11th - 16th
Beach Club Villa Studio: 381 sf $225 a night $1,155 for 11th - 16th
1 bed stand. view AKL Jambo House: 710 sf $375 a night $1,965
1 bed stand. view AKL Kidani: 807 sf $375 a night $1,965
From what I can figure out online, a one bedroom at Jambo House has one bathroom (but the fabulous lobby); a one bedroom at Kidani has two bathrooms (and a better pool/water play area.)
A one bedroom at Kidani would give you all you wanted, almost 300 sf more, animal views from many areas (not your room) and would cost you about $310 less.
(One big "watch out" - if you rent points, you cannot change the reservation.)
