There were many circumstances that resulted in changing the current conditions of the hotel. In 1940, Thomas Rowe passes away and, in the midst of World War II, the American Army takes over the hotel and transforms it into a military hospital. Later, it becomes home to the Air Force staff, and a year later, it is repainted to resemble military colors, such as shades of green. After the Air Force utilizes the hotel grounds, the Veteran's Administration assumes control of the building. In 1969, the building is in dire need of improvement and William Bowman purchases the building and repairs it for 7.5 million dollars. By 2012, the hotel was fully modernized and remodeled.
There were many celebrities, films, and sports teams that visited the Don CeSar Hotel. For instance, FDR, F. Scott Fitzgerald, and Al Capone were all guests of this hotel. The New York Yankees were also affiliated with this hotel, as they vowed to spend three years at the hotel during their training. Robert Di Niro, James Woods, and Tuesday Weld filmed their production of 'Once Upon a Time in America' at the hotel's location. Tom Petty and the Heartbreakers choreographed an MTV production at this hotel as well.
