You don't give ages, but I'll give you my ideas.
FW Cabins - sleeps six, full kitchen, one bath, bedroom with double bed and bunks, murphy bed in living room. Maid Service. We stayed in these twice when our four children were younger and loved them and the campgrounds. The kitchen was nice for a quick breakfast.
I think a standard room at any deluxe except AKL or WL will give you a day bed (twin size mattress) to put five in a room.
POR has a trundle that pulls out from under one of the double beds, but it is designed for a smaller child (maybe 10 or under).
We have chosen the connecting rooms with our teenagers the last few times and love it. We do not feel like we are separated at all. If anything it's a little like having a suite. We keep the door open between the rooms, even at night. The BEST part of two rooms is two bathrooms. Wonderful with a bunch of teens!
There's my two cents!
