We went in August and September and at various times. From park open until about 9:30/ 10 AM was always the shortest wait (maybe 20 minutes) but even at noon we lucked out and it was 30, and then again later in the day it was around 30 minutes or less again. Obviously this can change from day to day so my general advice in your case would be to RD TT, then head over to Soarin'. My best guess is you'd be on Soarin before 10 AM and looking at maybe a 20 minute wait. That early, you're really just waiting for one ride to end so they can load the next 3 theaters. The line moves fairly quickly now that they have 3 theaters.
