Hughes planned to personally oversee planning for the Landmark's grand opening; Robert Maheu, who had worked for Hughes since the 1950s, said "I knew from that point on that I was in trouble. He was completely incapable of making decisions." Hughes and Maheu never met each other in person due to Hughes' reclusive lifestyle. Instead, they communicated by telephone and through written messages. For months, they had intense arguments regarding the Landmark's opening date. Maheu believed the Landmark should open on July 1, 1969, but Hughes did not want to commit to an exact date for various reasons. Across the street from the Landmark, Kirk Kerkorian was planning to open his International Hotel on July 2, 1969. Hughes had wanted the Landmark's grand opening event to be better than Kerkorian's, but was concerned that the opening night would not go as planned. Hughes also did not want the opening date to be publicly announced too soon in the event that it should be delayed; Hughes wrote to Maheu: "With my reputation for unreliability in the keeping of engagements, I dont want this event announced until the date is "absolutely firmly" established."
