I thought the same about the hours that went in to those teasers. Especially as they had basically nothing to do with the actual event itself in the end.
I suspect this was a case of being “all in” as it was a huge opportunity for them, and held the potential to open them up to the rest of Merlin and the industry as a whole.
A bit of an investment in self marketing I think - but everyone wins, they produced some great content to showcase what they can do, and TP got some high quality teasers (all be it a little off piste).
Well done to all of them. Although I’m not too keen on the YouTuber marketing stuff, I think they produce some great content for the park.
