I just returned from a 4-nt stay at All-Star Sports. Any time we left the resort for a theme park regardless of the time of day, we had a bus that took us directly to the park. I don't recall ever waiting more than 5 minutes for a bus to arrive if it wasn't already loading when we got to the curb. Maybe that was just very good timing on our part.
One day we returned to the resort from Magic Kingdom mid-day. We had a direct bus to Sports that did not share with any of the other resorts. It was a VERY busy day at MK. The next day, we did Epcot. At park closing again there were dedicated buses for each resort. The next day, I left Epcot mid-day, but the bus from there went to all three All-Star resorts stopping at Sports > Music > Movies, and we did sit at the depot for a while even though it seemed like our bus was full.
Leaving MK after 1am one night, the drive back to Sports took 12 minutes once we got rolling.
Keep in mind last week was a very busy week. The first week of November isn't likely to be busy, so returning from the parks your bus may visit all three All-Star resorts.
We were pleased with the transportation at Sports.
As a by-the-way, I'll echo what bookgirl said about both AoA and DTD. Bad bad bus service in my experience. Long waits. In Dec at AoA we were heading for Epcot about 11:30am and there were about 3 buses worth of people stacked in the queue with nothing on the horizon. There were two CMs standing around with iPads doing .... what exactly I have no clue, but they weren't being helpful. Thankfully we had our car and all loaded up for the quick trip over, but it wasn't very convenient because we had two power scooters that we had to load up, AND our vehicle was parked in Egypt, I mean Little Mermaid, and we were trying to make an ADR.
