The choice really has been made for us, being a family of five also. We've done POR on our last two trips. (...and POP with the kids and my wifes parents the two years before that)
The alligator bayou rooms at POR are the only moderate level rooms that you can find that sleep 5 without spending a lot more on a suite somewhere (yes, even at the values)
I would love to try out a different mod level resort on our next trip though. When either my or my wife's parents go along, it makes things easier for us to try a different resort, since we all can't fit in an alligator bayou room anyway. We just get two regular 4 person rooms and one of our kids are in the grandparents room.
I've heard great things about CSR, and want to try it next time if it works out, and if the kids like the idea.
For what it's worth, we have loved POR, even though the kids would easily take POP as well. They just aren't choosy on that stuff and love both for various reasons. POR has great rooms with queen beds, but a more laid back (not Disney in your face) kind of feel, but the bus service definately takes longer, and the resort is HUGE so it can be a long walk to the main building/main pool. The resort is lush and beautiful.
We love the vibrant look and feel of POP as well. Bright, loud colors and fun theming. Double beds though. Good food court, but busy and loud. Very fun atmosphere. Very much Disney, all the time.
