Hi Michael,
You must be very excited about your upcoming trip to the Walt Disney World Resorts. I love All Star Resorts as they are a great value for the money.
First, the buses, no matter where you are staying, generally travel between the parks and the resorts every 20 minutes. This picks up in frequency around park openings and closings so that no guest is waiting too long.
Second, you really never know when a bus is going to come or just left so you must factor extra time into the equation when trying to make an Advance Dining Reservation.
From All Star Movie to Animal Kingdom is about a 10 minute ride. Downtown Disney will take about 25 minutes. Disney's Hollywood Studios will take about 15 minutes. However, I recommend you are at a bus stop one hour prior to guarantee you will make the bus. For the early bus to Animal Kingdom, I recommend you check with the concierge at All Star to see what time you need to get the bus.
Wishing you a magical vacation!
Beth
