We are also a family of five so I understand your concerns. My first pick would be Portt Orleans Riverside. We have stayed here many times and we have loved it every time. I would actually pick this over a deluxe, mainly because we don't spend much time in the room anyway.
We have also stayed in two rooms in a value and it was actually nice because we had more space, and an extra bathroom. There were six of us on that trip so we had to book it this way to fit our needs. The suite was going to cost us more because at that time they would not apply a discount code to a suite. I'm not sure if this has changed.
This next trip is a little different. For the first time ever with all of us going plus a new boyfriend of my DDs, we have decided to stay off site at Bonnet Creek. We are booked for 7 nights for $840. Total!! Sure, I will have to pay to park, but I will still be saving so much money, and this is for a two bedroom suite, with everything we could ever need right there. I couldn't rent points for that at a DVC resort. They also have a bus to if you don't want to drive. Bonnet creek is stil on Disney Property so it's not like it is out of the way. We always drive to the parks anyway so this was a non issue.
I'm all for saving money, but when it comes to Disney I have to do what will make everyone happy. DH is finished being crammed into a little hotel room so I must make my Prince happy above all or we won't make it back down there.

He is excited about our next trip.
What ever you choose to do, I'm sure you all will have a great time! Have a safe trip!
