Since I got to see AC for the first time this week I'll post a short review.
DCA was on my second day and I slept in and didn't get there until about 9:30am. I started by riding Monsters Inc. because the line was short. I was trying to time things so when I got to AC the Spider-Man show would be starting. So after MI I walked to AC via the GotG:MB side. MB's line was all the way back to the Hyperion wait line area, so I didn't wait for that.
I pretty much walked past Pym's, and the Iron Man m&g under the Quinjet and went straight to the area near WebSlingers to watch the show. It was cool to see it in person. After that, I checked out the Sanctum and took a pic at the hole thingie and after seeing WebSlingers at over 90 min I left AC. There's like nothing there to do if you don't ride WS. It didn't seem worth the wait and seemed like something I'd rather do with my family than a group of strangers. My nephew will probably enjoy the land as he loves Marvel characters and would love to meet them.
After that, I rode RsR (which just came back from a breakdown so the line was short) and then ate lunch, did Mermaid, walked around Grizzly Peak, then left DCA around 2pm and never went back.
