Here you go guys, I made a google map for ya. Where it says Epcot in red is well Epcot , and where it says Commons the commons are under the C and O. I dunno how long it takes though.
Takes around 15 minutes, 20 at most to get to Epcot. If I remember right I used to get a bus around 10am to start at 10.45am as you have to take into account the time it takes you to walk from costuming to your location. And depending on what country you're from that can vary! Like France and Morocco could probably take quite a while! There is a bus you can catch from costuming but I often found it quicker to walk rather than wait for the bus! Plus you could sometimes get stuck walking behind the character bus and have the joys of the lovely song it plays being stuck in your head for the rest of the day!!! ;D
