We have a ressie for 5 (DW & me plus DS 7, DD 5 and niece 10) in a deluxe bunk bed room at AKL (savannah view). In the deluxe rooms at AKL you get a little more space, and with the bunk beds, the floor space is opened up a bit more. AKL continues to have great WOW appeal for all of us, and since this is to be my niece's first visit, we thought this best for our first few nights. After AKL we join the grandparents (for a party of 7) in a 2BR at BWV.
Other options include most of the other deluxe resorts, which have a number of rooms with daybeds in addition to the two queens. WL I know also has bunk bed rooms and is nice and close to MK. FW cabins would definately have beds for all of you, but transportation-wise is pretty remote. And of course you can always rent points from a DVC member and get a palatial 2BR, but that gets expensive for weekend nights (very affordable for Sun-Thurs tho); this option also has the advantage of full kitchen so you can save on breakfast & snacks, plus in-unit laundry facilities so you can pack less.
Good luck to you!
