Part of your decision may be based on the ages of your children. We also are a family of 5. POR is great with the trundle bed. It is very small and you will not have much walking room once you pull it out. We will probably no longer stay here, kids are 14, 10 and 7. We just need a little more space. The cabins give a double, I believe, and bunks in the bedroom. There is a murpy bed in the living room area. Every kid gets his own bed, that is nice. The fridge is handy also. The only draw back is it is a cabin. I am not the camping type. There is usually a significant cost difference between a room at POR and Fort Wilderness cabins. Also, at POR there will be an extra $15 charge per night for using the trundle bed. One other option is to get two rooms at the All Stars depending on the ages of your children. That means four beds, two tv's and two bathrooms. You can also stay as a family of five at any of the deluxe resorts except WL and AKL. Good luck deciding.
