It's about 10 minutes to the bus stops.
We really liked the resort, it's beautiful, the theming is incredible. The pools and the characters and landscaping were truly wonderful. Loved the food court, not a bad meal tge entire time. BUT, we have a large family and need 2 connecting rooms, that's why we stayed in the LM rooms, but I found the distance from the food court and bus stop to be inconvenient. It wasn't so much a problem in the morning when everyone was energetic and excited to get to the parks, but at night after a very long day in the parks, that walk seemed never ending. My husband started driving our suburban to the front each morning and parking near the bus stop and then we would all drive back over to the LM section when we got back each night.
Glad we got to experience it once, but I'm sure we will head back to All Star Movies for our trip this year. We stay in the Mighty Ducks section there and it is , literally, across the street from the All Star Music bus stop.
