we were there for opening on Sunday, we were about the 10th family in line, we got in line around 9:45, for the 10:30 m&g. The characters did go in once while we waited, but they were gone for seriously 2 minutes and back out again.
The "director" thing that is out, he entertains the kids, I think is really dumb, you don't have to be in line to see that, and everyone is standing around watching, and being that it right by the exit of muppets, it became very crowded in that area.
Here are some of our pictures.
