I'm expecting pretty much what everyone else has said, however, I really hope we do get a refreshed TotT and Sub Species 2.0. Because it is quite an insult to make guests pay (I believe) like £25 (?) for 3 mediocre mazes we've already done with a lack of actors, yet stunning theming. I also am pretty sure the return of HoM has been confirmed too.
I also really hope we see the return of The Welcoming, as last year (sorry not sorry for the pun) it was a welcome
addition to the event, however, I hope they either get rid of the blindfolded section and make it an 'old-style' scare-zone or just lower the entrance cost of it as it wasn't worth the amount they were charging. I also think it'd be great to see 'Wicker Man: Alive', basically once the sun starts to set have all the Wicker Man characters out roaming the area (with themed lighting and smoke) as well as the fire breathers and jugglers we saw on the opening days and preview events.
In all honestly I really really want a new maze for this year, but then again I can't see Towers doing it, although, I'd love to see it happen!
Finally, I think this year I just want MORE SCARE ZONES. I can 100% see Freak Show returning again (which I'm happy with because it is great) but I feel Dark Forest and Forbidden Valley especially feel very dull at Halloween and just look like no effort has been made to make it ever so slightly 'spooky'. So whether or not more scare zones are added, the least they can do is chuck a few smoke machines and par-cans across the areas. Fingers crossed this year is better than lasts years disappointment.
