We always rent as well, I think it is much faster driving ourselves from our resort to the parks or when we are park hopping than having to wait for a bus.

All of the parks have trams from the parking lot to the main gate and they come one right after another so there is usually no waiting.

Most of the rental car angencies are located right at the airport so there is no shuttling back and forth to get your rental. When you return to the airport the rental car drop off is right there in the parking structure for dollar rentals anyway.

P.S. Here's a little tip it has worked for us for the last 3 years. We always rent from dollar. I always book a mid-sized car and every year when we check in to get our car they ask us if we would like to upgrade, we always decline and low and behold our car is never ready and they always claim that they do have a minivan ready at no extra charge if we wouldn't mind taking that. This happens every year!! Sounds like with your family of 5 you could probably use a minivan.;)
