Just had to say I went to HHN for about my 5th visit (thanks to FFP), and things are much, much better since that disastrous first Friday night last week.
Since we also have APs, we entered the park around 5:00pm, went in, got our HHN wristbands, and headed down immediately to Exorcist, where we were about the 7th group in line (excluding Express). Was able to go directly to TCM. Then went upstairs to H4 (mainly because we had already done HH and Pandora a lot), and was happy to discover they opened the maze at about 6:45 (it's not scheduled to open until 7pm). Because of this, we were able to be out of that house by about 6:55, so we decided to book it right to HH and Pandora, and was even more surprised to find both mazes were basically walk ons (despite being posted at 45 minutes... that just seems to be the initial wait time they post when the mazes open). We did both, Pandora twice. Headed back up to Bride, which also had no wait, and was then done by just before 8, so since we were already there and on a roll, headed to TWD just to be completists. They were letting people in line by 7:45, but the maze itself didn't open until 8. We could've gone to Terror Tram right then with a 10 min wait, but we were starving, so we headed down to TCM BBQ to eat. It was about 9 by the time we got to Tram, and it was posted at 30 min, but it really took about 15.
So without any express, we were able to do every single maze by 9:30pm on a Friday night. Being inside the park early with an AP and H4 opening early definitely helped make this possible. But even so, when we left the park at 10pm, the longest line in the park was Exorcist at 90, and most of the mazes were around 40-50 min, so if you were willing to wait in just a few longer lines, it could still be done. A huge improvement from those 2-3 hour waits just a week ago.
I"ve also been hearing great things about Knott's... I'd say they win just because of the more varied food offering, and having so many more shows... two things that HHN just can't seem to ever get go. At least they're stepping in the right direction with the food, but having the Animal Actors Stage just sitting there unused all these years is pretty inexcusible. Even SFMM's FF has more shows, for goodness sake. IMO, if they want to remain competitive, they're really going to have to make more improvements in experiences other than mazes.
