Agree with the RD strategy. When we were there...we walked straight back after RD and waited for 5-10 minutes. Even if you get there shortly after rope drop and you can get to TSM when the wait time is <30 min, I'd save the FP. Just seems like a waste to me...especially since you only get on FP for the 3 top tier rides. Get there early, ride standby...and save that FP for ToT, RRC, or even another ride on TSM in the afternoon.
