After communicating with fellow staff members, I have been reliably informed that Terror of the Towers is the best maze this year, followed by Carnival of Screams. The Sanctuary isn't worth the wait or money, and Zombies remains un-opinionated as it was closed (but uses pretty much the same scenery/props that it did last year, so it should be roughly the same)
For those who aren't aware, the locations are as follows:
Carnival of Screams is on the path going past Sonic Spinball up to X-Sector (As Carnival of Screams takes place in and around the 'Goal striker' building).
The Sanctuary & Terror of the Towers are both located inside the towers, and can be reached via the old/normal Hex exit.
Zombies Scarezone is located just before you enter the towers grounds, at the little intersection/confectionery kiosk just outside the main archway (Just down from the old Hex exit/where the other two mazes are). You turn left here and make your way along, and it's on your right, in a staff-path that connects through to just outside Dark Forest
