The park should make an early morning tour for the 50th (before park opening), charging something like $39.95, and one of the tour items would be to view from the 50 foot deck (only for those taking the tour, thereby making the park pure profit). Other tour items could be backstage of Kings Island Theater (some really cool things from the past used to exists in storage), phantom theater, train storage, maybe memorabilia from the past 50 years etc.
If the rumor is true about a certain coaster being torn down at CP after this season to make room for their new coaster, they could salvage the external ADA elevator lift from that coaster and relocate to KI for the 50’ platform for ADA tour guests only. One daily small tour group of about 15 people paying $40 over the course of approximately 90 operating days could generate the park approximately $50K of pure profit in honor of the 50th anniversary.
