We usually hit the Soarin' fp machines first and then go into the standby line so that we can ride twice. This time we skipped it because we had already been on Soarin' earlier in the trip and planned to head over to The Seas to spend more time there that morning. It paid off getting those 2 first class flights.
As a side note, after we had done The Seas, we walked over to the Imagination Pavailion and were given the magical fast passes, so we were able to do Soarin' one more time that day.
