I always drive down and I always park our car and don't get back in it until we leave. It really is a matter of preference, I don't like to drive especially in a different town then the one I live in. Driving around Disney property is pretty easy, there are plenty of signs but I just prefer to let them drive me around. We don't mind the buses, even if we have to stand it's not a big deal and if we want to have a refreshing adult beverage (which we do) we don't have to worry about driving. We drove to a park once, we were doing a split stay and it was move day, we knew we were going to AK that day and we were up early so thought what the heck, let's drive and do rope drop (we aren't rope drop people). We were there around 8 on a 9 opening day. Where we parked was just about the same distance walking wise as the bus stop was. We only stayed until around 2:30 or so that day so when we left there really wasn't any traffic leaving the park but we really hated not being able to grab a beer if we wanted one.
