I'd really love to see some themed-style events added to the park's calendar. Alton Towers have had great publicity with their "Oktoberfest" event, something like that would be great for Drayton Manor given the family clientele they attract, and the fact that this could serve as education to teach younger visitors about different cultures. Themed music, cultural food and entertainment would be all that's needed - and it'd give the triangles near The Buffalo some sort of use.
Although the floods were incredibly sad to see, I think it's good that the park have shared updates in the form of images and videos from this across their social media - I think it will draw more people to the park to support them, and also inform more people about the park from it being shown on the news, etc. I think although the floods were sad, we'll see lots of small renovations across the park this year, to set a good base product for the 2021 season where hopefully the park can get back onto that success cycle as a family park, like they always were.
The 70th anniversary season hasn't technically started yet but we're already seeing indicators that this could be widely celebrated with 70th anniversary flags flying outside the Humble Pies and at the front of the park - I think some good events, as well as the improved entertainment will make this season successful. Hopefully some good renovations and minor issue fixes will help make the park look a little fresher and set the tone for a successful 2020 season. I think if this season is successful, Drayton could hopefully be in a position to make big changes for 2021 - I'd like to see a whole family area, use the existing thrill rides and add some others to make a total family area.
