Called the hotel directly today to ask about the shuttle service.
The lady didn't have much first hand info., but told me that they do not own the shuttle and it can make several stops.
In her words, "Universal is about 10 minutes drive from us, the shuttle will take about 25 minutes. Disney is about 15-20 minutes direct drive and the shuttle will take about 30 minutes."
I would be wary of the times, as she didn't know a lot about the shuttle. She was very nice though, and said she needed to find out more about it and to call back tomorrow if I needed more information.
