In all honesty, I found the tour to be much more beneficial than the actual event itself.
I'm debating on posting a review (of the event) because I don't want to be a Negative Nancy - but I cannot say enough positive things about this tour. Our tour guide Ashley (I believe) was also fun, and you could tell she was a fan of the IP's and not just reciting some random scripting as she took us through the houses.
This tour - if you haven't done it - really gives you an opportunity to see all the hard work that creative put into the design of the houses. From the set, to the layout of the scares, as well as some backstory and bits of trivia. These are all things that you don't get an chance to appreciate when being rushed through the houses during the actual event itself.
So glad I was able to get a last minute tour booked. Highlight of my HHN experience, hands down.
