It's always a very fine balancing act with marketing anything like this kind of thing - put things out too soon and you end up losing any monentum before it's even opened, put things out too late and you don't have the impact on opening. We need to remember that marketing isn't just simply TV adverts and posters, and also that the approcah to Wicker Man will be different to the approach to The Smiler as, athough they are both Secret Weapons, they are very different rides.
When you take everything into account, there has already been a substantial amount of marketing for Wicker Man. The inital reveal on the Towers Loving Care account; the signage on the construction walls surrounding the coaster throughout last season which will have been seen by anyone who visited the park; the labelling of SW8 on the 2017 park map; the publicity stunts by the London Eye; the inclusion of The Welcoming at Scarefest which introduced us to The Beronan and their story; the various teaser videos published on the Resort social media channels; plus the two major marketing drops this year - one in January which saw just about every major media outlet, including the BBC, ITV and national press, cover the announcement of the ride's name, and the drop just a couple of weeks ago with the first official images which saw similarly wide ranging coverage. Don't forget that The Sun are due to begin their usual free ticket promotion shortly and that will almost certainly centre on Wicker Man too pushing the ride firmly into the general public's consciousness.
As for the TV advert, we may get it just before park opening, or we may not get it until May time. Son't forget that Towers will need Wicker Man to draw in people all season long, not just in March, therfore they will have a marketing strategy which reflects this and see some advertising reserved for just before key trading periods such as the May half term and the school summer holidays.
However, I do strongly believe we will see something towards the end of next week, even if it is in the form of The Sun promotion, or a wider campaign.
