Me and a few friends went to Universal Orlando last week on a thursday night to see the AvP experience. I have to say, it was pretty awesome. It was the first thing we went to when the gates opened at 6:30 and waited about 35 mins to get into the attraction. I loved it, every bit of it. Seeing it on youtube does not do this thing justice, it was very authentic, and for a halloween house, a 10/10. Of course given that I am 37 and dont really scare all that easy it wasnt scary to me but rather "oooh look at the detail" "Oh wow Predator looks so lifelike" things like that. But, lots of girls were screaming and jumped a few times. It was about as realistic as an attaction could get. My only complain would be that I wish instead of going thru it in a long line, it was done where you can go through it in small groups, to get a better overall experience. O well.
At one point the wait times for AvP were longer than the walking dead. Over 2 hours! So if you are wanting to see AvP be sure to do that FIRST. The lines grow fast and will exceed 90 to 120 minutes very quickly. Also, if you plan on going be prepared to be checked at the gate like you are at an airport. They scan you, pat you down, make you take every little thing out of your pockets, etc. plus massive police presence is there. Which I dont really mind because I felt pretty safe thats for sure.
Oh, and bring $22.00 with you for a really sweet exclusive AvP shirt you can get in the main shop there. I am at work and can't take a pic of mine, but this image attached is the shirt that is for sale there. On the back it has a "Halloween Horror Nights 2014" logo by the neck.
