I also went on 10/18 and it was horrific and not in a good way, either. I lived in Orlando 10 years ago and since I worked in the industry, I was basically broke and could never afford the $35 to go. I always figured "someday...". Now I live out west and I was on vacation visiting my family in Florida and my brother and I decided to go.
We got in at 6:15 and the first two houses on the left after entry (Nightmare on Elm St and Dead Silence?) both had 60 minute waits. We went straight to the Mummy, split up in the single rider line, and were out in 7 minutes. Not bad. We then went to Chainsaw, waited 30 minutes, were absolutely unimpressed with the house and then looked at each and said "We waited 30 minutes for that?".
We resigned ourselves to the wait times at that point. We then got in the posted 90 minute line for Friday the 13th. I was shocked when I saw the line snake around into the backstage area. As for the house, it was boring and neither of us were scared. We ended up doing MIB and walked around. By 11:00, the lines were a minimum 90 minute wait and since the wait times didn't pay off for us with the two houses we did do, we thought we would just leave and get a bite to eat. Food at Bubba Gump's was great.
Unfortunately I paid the $70 for HHN. I can't believe all these years I wanted to go and then I had such a poor experience. I always thought Universal could pull off something like this far better than anything local. Now, I will definitely take a look at the local fare instead. I have a supposedly haunted insane asylum within driving distance...might be fun. There was lots of line jumping that night, too. The whole event looked like a giant money grab by Universal to sell overpriced alcohol. Judging by how boring the houses were, I think people must be drunk to get something out of them.
I've written a letter to send to Universal's guest relations, but I haven't sent it yet. I don't think they really care about my bad experience. I know I won't be going to USO anytime soon and definitely not until I can figure out a creative way to get some value out of the $70 I gave to Universal.
