We are a family of five. POR/AB holds families of five with the trundle. We spent 10 days in a AB room. After 10 days in that room we were not feelin the love for each other anymore

I still love POR though! After that trip we bought DVC

ASMU has family suites that apparently hold 6 and are quite nice or you could get 2 value rooms if you want to spread out and depending on the age of your kids.

Another option is to rent DVC points off an owner.
