Starting in mid-July, all Kings Island locations will only accept credit or debit cards or an online payment form like Apple Pay or Google Pay, a news release from park spokesperson Chad Showalter said. For visitors without card or online-based forms of payment, the park will offer kiosks in five locations across the park that will transfer cash to a card which can be used anywhere, not just at Kings Island or Soak City Water Park.
