POR had two areas, French Quarter and Riverside. I think both have nice pool areas, but FQ has the "fancy slide" that's a hit for kids.
Riverside has a trundle and sleeps 5, FQ sleeps 4. Now the rooms aren't huge, but usually when we hit POR, we've got 3-4 in the room max.
I've stayed at the cabins at FW also. We had ( I think 7 ) and it was very tight. We had a nice time, but I felt like everything was really far away. For instance, you had to take an internal shuttle to get to the main bus stop to go anwhere. It seemed like it took a really long time to travel. Very nice resort though. Also, the MK area isn't my favorite, the only thing "close" was MK. They are very different resorts and each has a distinctly different feel. Even though, the FW cabins are considered "deluxe" I'd chose POR over them.
