We have just spent two wet days there (a Thursday & a Friday)... Having tickets specific to a day meant the park was still surprisingly busy. 
Pirates never had a queue longer than 35 minutes & you can usually get TRON Fastpasses throughout the day.  We managed 3 rides on TRON over the 2 days, only one with a FASTPASS. 
  
Longest queues we saw over the 2 days were for Soarin' & the Seven Dwarves Mine Train.  Both were frequently well over an hour. 
 
Fastpasses for within an hour... this was a surprise. 
 
Notice the umbrellas... a very wet two days. 
 
Apologies for the quality of this one... turns out iPhones don't enjoy two days of wet weather very much...
