From the Contemporary, the bus will travel to the Polynesian, Blizzard Beach (drop off only), and then Animal Kingdom. The return route is Animal Kingdom, then Blizzard Beach, then Contemporary & Polynesian.
It should be noted that you can board most any bus from AK to get to Blizzard. Just double check with the driver first, as some routes might not go there. (ie: AK Lodge & All-Stars do not)
