We went last week and it was very manageable. Packed until after Wishes, then we went right to Space Mtn (as did MANY others). Long line because they had to explain to every other person in line that they needed a wristband, what qualified them for the wristbands, where to get a wristband if they qualified, why they couldn't ride if they didn't qualify. Once inside, it was a walkon.
Throughout the rest of the evening, there were primarily lines in Fantasyland, at least early when we were there. 20 minutes for Peter Pan, 30 for Pooh (we used FP). But the rest of the park was pretty much walkons - we also did Buzz, HM, POTC, Thunder and Splash. They were allowing you to just stay in the boats and ride Splash a second time if you wanted. Of course it was 40 degrees and windy, but still...!
