The resort was developed and owned by the Spackman family who owned it from 1926-2008. Originally entitled Ideal Beach, the amusement park began as an actual beach with a bath house and refreshment stand. In 1927, its first thrill attraction opened, and from that point onward it began to expand. In the 1930s and '40s it was popular for its Ideal Beach Ballroom, where big name bands would be featured. More recently it has been known for its rides and vacation cottages. In February, 2008 it was announced that the both the amusement park and Indiana Beach campgrounds were sold to Morgan RV LLC.
In 2011, former and current employees staged a protest due to working and safety conditions at the park, claiming that "Rides are continuously closed, or many times forced to be open using rigged components because the company will not or cannot pay for the parts that will allow maintenance to fix them properly.". An inspector from the state's division of Homeland Security investigated as a result of the protest and found no major safety violations.
It was reported in December 2012 that Morgan RV LLC had sold 11 of its properties to Sun Communities Operating Limited Partnership LLC of Michigan for $135 million. Among the listed properties was Ideal Private Resorts LLC, whose website includes Indiana Beach Amusement Park and Indiana Beach Accommodations as destinations. Calls to Morgan RV LLC requesting comment, including confirmation or denial that all or part of Indiana Beach was included in the sale, have gone unanswered.
In January, 2013, local news affiliates reported Morgan RV LLC was delinquent paying property and innkeeper taxes totaling approximately $347,000 to White County, where Indiana Beach is located. The county had received a payment of $11,000 towards $191,648.49 of the innkeeper taxes in arrears, but no payments have been received for the property tax portion of the debt. On March 19, 2013, a spokesperson for Indiana Beach stated Morgan RV LLC had paid the entire innkeeper tax debt in arrears and her statement was confirmed by a White county official. A local news affiliate reported on March 20, 2013 that Morgan RV LLC had completely paid their tax debt arrears, including the past due property taxes.
Lodging at Indiana Beach includes hotel, motel and cabin accommodations with varying prices, sleeping capacities and amenities. There are also two campgrounds containing approximately 1,000 camp sites.
