Congratulations on your new baby!!!
Will there be any other children with you? We've stayed at the All Star Movies twice now, and we'll be back in October! We had a room in Love Bug, and 101 Dalmations. Both rooms were very quiet, and a quick walk to the food court/bus stop. Our rooms did not overlook the courtyard area, so maybe that's why they were so quiet. Bus service was wonderful!!
We've also stayed at Coronado Springs and Port Orleans FQ. Both were very nice; Coronado Springs was more spread out than Port Orleans FQ.
I would also suggest bringing your own stroller, especially for walks around the hotel (and if you go visiting other hotels)!!
