We do have a lot of character dining. I believe Ohana, Chef Mickeys, 1900 Park Fare and Wilderness Lodge are all in different resorts. So is it faster to there by using a car versus shuttle? If I'm already at the park, wouldn't it be easier/faster to get on a monorail and get to the hotels? I like easy and fast especially when traveling with kids.
I just checked the price for a rental and I found $135 which isn't bad at all but if I don't really need it, that is also money that can be spend at Disney.
