Unrelated to any specific IP or original spec, and not to open a can of worms in regard to the dreaded yearly ticket debate, but I've been collecting my notes from the Haunted Attractions and Halloween Show, and forgot about the seminar I attended
about upcoming trends that T.J. Mannarino was a part of. I noted down he mentioned explicitly evolving an event over the course of a season to encourage repeat visitors, particularly offering limited discounts, special events on certain nights, basically something to entice a person to come back even if they've "seen it all".
Not sure they have really done this much in the past (beyond closing night special experiences, and the occasional unannounced celeb drop in), so it felt odd he mentioned it out of pocket, particularly in a panel meant to forecast predicted trends and patterns for the upcoming haunt season. Again, not to say this wasn't just something they were batting around at a blue sky level that doesn't amount to much, and it was just in his mind at the time, but still could be interesting to see more limited offerings on the table.
(he was asked point blank about Dark Universe by the owner of Netherworld Haunted House and basically read verbatim the press release, lol, so he knows when he has to be tight lipped, haha)
