Well, my thoughts are that a launch coaster and a Runaway Mine Train type ride would really benefit the park.
I think a launch coaster would be brilliant for thrill seekers as Drayton Manor needs a new thrill ride after lots of attractions for different age groups than thrill seekers. I think a Runaway Mine Train type ride would be great too as they are really family friendly and fun for all age groups. The theme is very strong and most people are familiar with Runaway Mine Train rides.
So, a new thrill ride like a launch coaster, (like Rita- Queen of Speed) would be great and also a thrilling family ride would be good too. I think we probably will see one of these attractions appearing sometime in the future, hope so anyway.
