Like the first reviewer stated, there is definite room for potential. It's disappointing that a place which is well-marketed doesn't live up to the online hype. I thought my computer was messed up when I couldn't purchase tickets online thru all 3 major browsers (Chrome, Firefox, IE), but it's just their website. I emailed asking to see what was up and didn't get a response back, so I instead had to purchase on-site. There is a $1 off if you refer to promo code WEB1, valid on-site.
The location is hard to find without the construction sign pointing you towards it. Literally is just off the Red Mtn and Alma School. There are parking people to guide you to the general area, some spots literally in-between salt mounds.
It's not worth the extra $15 for the zombie ride-- was terribly under-whelming and the left side seemed to get more shot opportunities than our side. There also weren't a lot of zombies- do they need more actors? Probably. Could the few zombies have been more intrusive on the vehicle? Most definitely.
I did enjoy both of the houses but Epic Fear was far better than Slayer's House. The website also mentioned a "Beer Cemetery" and a magician on Sunday's, but neither were found. One employee didn't have a reason for the bar to not be open, I didn't bother asking about the magician after someone ahead of us in line asked and the gal had no clue. The Scarizona people have a lot of improvements to make me want to come back.
