I attended Universal's Halloween Haunt this year (the Friday that rained, October 12th) and I have to say that Bill and Ted's was great. Universal did a good job this year. While it does not match some of the previous ones they have done they are getting better. The Hollywood version is only returning now after being down for a few years.
Remember it is harder for Universal Hollywood to host these events since this studio is still very active with actual movie making than the Orlando park. The Orlando park can use the whole park for their haunt while Hollywood has to use less due to the filming.
Thanks for the video post, it reminded me of what a great time I had there.
