We were there in april (during Easter) and RnR, TT and EE all had a day when the FP were sold out by early to mid afternoon...all of them had multi hour delays when getting a FP on the really busy days (ex: get FP at 10:30 for a 4:30 ride). ToT never ran out when I was there.....I know this wasnt the summertime...but if the crowds do get REALLY busy..there is a chance the "big" rides, especially EE, will run out...get them early to be safe !!
