It's funny how catching these houses underneath different circumstances can either completely sink them or make them magical, hah. Hellblock was definitely something they had to smack together on the fly but I honestly consider it one of the highlights for the year just to how I experienced it.
A friend and I hit HHN 31 by using the hotel guest entrance to get into the park. We didn't realize that it was a Stay and Scream area, so we went up to the TM at the front, asked about it, and they were all "Yeah, we just opened, go in!" So we go in... find ourselves going through queue... "Huh, are they directing us to the exit near Fallon to bypass the entrance crowd?" Then it turns out, no, we're entering through a house, first thing we do, before we even hit a scarezone.
I know Universal tries to sort of have a gauntlet at the front to go through for guests, and I know it'd be a nightmare to send everyone through a house to enter the event, but Jesus Christ that was a glorious surprise and a real way to get our feet wet for the evening. Never going to forget Hellblock for that.
Coven was a bit of a disappointment (that I'm looking forwards to having rectified with the New York scarezone this year...) but I did like the gradual progression of the witches within. Didn't get enough 20s for me.
... That Tribute Store that year absolutely ruled, though, beautiful beautiful experience. I'll be disappointed that this year's store is smaller, but at least it's still there.
