I'll give you another hint, and hope that I don't spoil my little secret. Instead of going on Soarin' when they let you in at 9:30, keep walking past Soarin up to where the entrance to the GCH is located. The last two times I stayed there, they formed a queue outside the hotel entrance. It's mostly hotel guests who are in line there, but at 5 to 10:00 they walk the whole line over to TSM and you get on the ride before all the people waiting in Sunshine Plaza. You'll see them sprinting over the hill to Paradise Pier as you are exiting the ride.
