This summer we walked over from the CCI. But before that we always drove. The summer before, we drove and first thing in the morning we drove right in to the Pinnochio lot without going through the garage. It was very easy and we got close spots. By afternoon, that entrance was closed. Don't know if they have changed it or not, but I put detailed driving and parking directions in my Embassy Suites Hotel review (link in my sig).
When we parked in Pinocchio, we usually took the tram, but we walked a few times too. My sister, who has a stroller, prefers to walk over from there.
