When the Landmark opened, it had a total of 400 slot machines.
The ground-floor casino was 14,000 sq ft (1,300 m²), while a second casino, consisting of 3,000 sq ft (280 m²), was located in the dome on the 29th floor; it was the first high-rise casino in the state.
At the time of opening, the ground-floor casino featured red and black colors, while the upper casino used orange coloring and wood.
The hotel contained 476 rooms and 27 suites for a total of 503, a small number in comparison to other Las Vegas resorts, which commonly had 1,000 rooms.
The tower included 157 hotel rooms, while the remaining units were located on ground level.
The tower used an octagonal floorplan, and the rooms in the tower used a layout that had them shaped like pie slices.
By 1977, the room count had increased to 524, before ultimately being lowered to 498 at the time of the Landmark's closure in 1990.

The Landmark's interior designer was Las Vegas resident Leonard Edward England, who designed the ground floor to include a colorful and primitive Incan theme, which gradually changed to a Space Age theme on subsequent floors.
The interior included $200,000 light fixtures, glowing, red-colored Incan masks, and a burnished metal wall sculpture representing a Cape Kennedy launch.
The interior also included 65 tons of black and white polished marble, and carved mahogany woodwork from Mexico.
In addition, the interior featured murals depicting the eight Wonders of the World, which included the Landmark tower.

After Hughes agreed to purchase the resort, he had an island built in the middle of the hotel's 240-foot swimming pool, which cost $200,000 and was the longest in the world.
The Landmark's pool included waterfalls and three carpeted bridges leading to its center island, which featured palm trees.
For the hotel, Hughes replaced 72-inch beds with 80-inch beds and had color televisions built into the walls of each room ahead of the resort's opening.

The Landmark's second floor was used for offices.
The tower's dome included five floors, although floors 26 and 30 were used by employees for maintenance equipment, elevator equipment, and dressing rooms.
The shape and strength of the tower's bubble dome was maintained by perlite concrete and steel girders.
The Landmark included a high-speed exterior glass elevator – located on the tower's west side and facing the Las Vegas Strip – which took people up to the five-story cupola dome.
Elevator Services was hired to install the Landmark's exterior elevator, capable of moving 1,000 feet per minute, allowing people to go from the ground floor to the 31st floor in 20 seconds.
It was the fastest elevator in the Western United States.
Hughes biographer Michael Drosnin stated that the elevator was prone to constant malfunctions, and that the Landmark's air-conditioning system "never really worked."
The dome provided wraparound views of the city, and was capable of holding over 2,000 people.
The dome included lounges and a night club, as well as the high-rise casino on the 29th floor.

At the time of the Landmark's opening, the showroom and the Cascade Terrace coffee shop were located on the first floor, while a steak and seafood gourmet restaurant known as Towers Restaurant was located on the 27th floor and a Chinese restaurant known as the Mandarin Room was located on the 29th floor.

In April 1971, plans were announced for a $750,000 expansion that would include luxury suites on the 29th floor, the highest in Las Vegas at the time.
Also planned was the remodeling of the casino and lobby, and the expansion of a coffee shop.
The Skytop Rendezvous, a piano bar and dance floor on the top floor of the tower, was reopened as a discotheque on February 3, 1975, specializing in middle of the road music.
The Landmark was the only major hotel in the state to have a discotheque.
When Morris' renovation began in December 1983, the tower contained 150 rooms, a number that was expected to be reduced as the rooms would be enlarged and upgraded to first class standards.
Other plans included changes to the coffee shop, new casin
