Bob Rinker graduated from the School of Hotel Administration from Cornell University in 1952. While there, he was the Dean’s Assistant and Managing Director for the Hotel Ezra Cornell. He made such an impression on his classmate, W. Dudley Child, Jr., that he was immediately hired as a manager in the Child’s Inter Island Resort business. Bob managed the Naniloa Hotel and the Kona Inn on Hawaiʻi island before settling on Kauaʻi in 1953 to manage the Kauaʻi Inn.
Once he was established in Hawaiʻi’s tourism industry, his career became a tour of the islands – and, indeed, the Pacific region. He was hired away from Inter Island to join Gus Guslander’s Island Holidays hotels in 1955, where he opened the Maui Palms Hotel. In 1957 Bob moved to Oʻahu where he and a group of investors bought the Pali Palms Hotel on the Windward side.
