I went on Saturday night and felt bad... Wait was pretty much a walk on, but while we were waiting to get on our boat, this woman behind us was telling the guy she was with how he was gonna have his mind blown by "the animatronic at the end of the ride." They ended up sitting right behind us on the boat.
Lo and behold, we get to the end and the tarp is up, no Indominus, and I just hear the lady go, "What the f*ck" really quietly. She had to describe it to him after the drop. All that hype for her friend (or whoever he was to her) to see it and... it's not there. Just a reminder I'm glad to have an AP, because people who come for a day for the first time in years and may not be able to come back for years, if ever, not getting to see the more amazing elements of the park is unfortunate despite being an unavoidable element of the theme park experience in general. (Even the dragon animatronic on Forbidden Journey was darkened out and not working!)
