We saw them at MGM's Crossroads area in early Oct., but I thought they were hidden. A CM had told us that they would be out at 2pm - when we got there we didn't see them. Had to ask the CM & she pointed to a little nook. Herc & Meg were all alone, so we weren't the only ones who didn't see them. They spent quite awhile looking at DD's homemade autograph book & giving her tips on where to find some characters. They told us Phil would be out with them at 3, but we had other plans.
There were about 10 different characters out in the area, spread out in pairs. The CM told us they came out at 2pm for 20 minutes, then again at 3pm. Not sure if this is normal though.
