I thought the crowds last week were slightly worse than I expected. On a scale of 1-10, I was expecting an 8, and experienced a 9. AK seemed to be having the biggest crowd problems to me.
That said, a little bit of planning makes the crowds manageable. Get there for rope-drop. Use FastPass. Take advantage of EMHs.
Also, be prepared to see some FastPass machines down for refurbishment. Space Mountain was down before we got there, and BTMR and Jungle Cruise were down while we were there. And FastPass machines for Splash Mountain ant Kali River were broke down at times. And, of course, FastPasses often run out for TT and Soarin' by the afternoon.
