We have been two times in the last three years in January the exact time frame you are talking. I can say that we got but didn't need the fast passes at all. Rides like test track were near walkons later in the day and 10-15 earlier. RnRc was about a 10-15 wait without fast pass, ToT was about 10 minutes. I would say the longest waits were for Dumbo, the cars on rails, and Peter pan. All were about 10-20 minutes. We never had anything over and like i said, many were 5 minutes or walk ons. If you do EE Buzz lightyears is a walkon for several rides before the crowds come in. It is the best time to go in my opinion because although the parks are not open as long, you don't wait around all day and get more bang for your buck.
