I think you should RUN to TSM, and get a fast pass. This is what my family did, then we got in line and rode it...the line wasnt very long...maybe 25 minutes??? then....when we got off the ride.....we got another fast pass for it. you can use your fastpasses anytime after your scheduled time, and our first one was for likr 10:15 am and then the second one we got was for around 6:30pm. so we did things that you didnt need a ast pass for, then 2 hrs later we got a fast pass for something else in the park. we usually get a fastpass for either ToT or RNR then wait in line for the other. this last trip, we went with another family. so there was 6 of us total (3 from my family, and 3 from theirs. there wass a boy who was 15 or so, thought girls were yucky still lol i was 20, but i still did things with him). well anyways, we got like 2 fast passes each for RNR, and then the parnts didnt want to go again, so we took their fastpasses, THEN the boy didnt want to go again, so I took his, and i went on in 6 times in a row!!!! it was just amazing!!! lol
anyways....back to what is going on lol, i think getting a fast pass for TSM is the best route, then make your way to see things that dont need a FP like the indy show, and GMR, and PLEASE dont skip OMD, a lot of people do because they dont want to watch a movie, but it makes me cry everytime i see that. that is the history of Disney, the reason we can go there and enjoy it so much. im geting goose bumps right now just thinking about it. i cannot think of anything else that would reqire you to have a FP....hope i helped in some way!!!
