It was running, for the most part, on all three of our Epcot days over the past two weeks! All of the animatronics were working. We loved the ride! One day we got the e-mail saying our fast pass experience had a change, and that FEA wasn't open. I'm glad we waited, since it was open within an hour.
Lines for stand-by were between 1 1/2-2 hours...much better than the 5 hours from opening week though!
