Ohio's biggest indoor water park is about to get bigger.
Kalahari Resort says it will double the size of its convention center at its water park in Sandusky.
The $22 million expansion will begin in March and add ballrooms, meeting rooms and an outdoor plaza.
Kalahari opened in 2005 midway between Cleveland and Toledo.
It bills itself as the nation's largest indoor water park and is the second largest employer in the Sandusky area with 1,200 employees.
