SANDUSKY, Ohio (WCMH) — Cedar Point will be closed some days in June due to a lack of staff.

The amusement park managers said in a social media post that it added more than 300 full-time, year-round positions, and a $500 seasonal signing bonus. Part-time wages increased to $20 per hour.

But recruitment hasn’t met demand, managers said, and the calendar had to be adjusted based on the availability of seasonal labor.

Cedar Point and Cedar Point Shores Waterpark will be affected. Guests can visit the online calendar for more information.
