Those invited to Vanderbilt Mansion were accommodated in lavishly appointed guest rooms, all of them furnished in 18th-century French style. Each room had its distinct color scheme, with the motif carried into the bathroom accessories. When the number of guests exceeded the number of guest rooms in the mansion, the overflow was housed in the pavilion.

Guests had the option of having breakfast in their rooms. The food would be served on special breakfast sets that matched the color scheme of the rooms. Those who preferred eating in the dining room found the small family table at the east end of the room covered with a white cloth and set with red china. In the center was a large swivel tray, or Lazy Susan, containing coffee and food for the meal. Guests were expected to seat themselves, turn the tray, and choose from it whatever they wished. If anyone was late, fresh coffee and warm food were brought up from the kitchen and placed on the tray.

When luncheon was served for the family or intimate friends, the small table was again used. If a formal luncheon was being served, the larger table in the center of the room, which could seat up to 30 people, would be set.

Details for formal affairs were arranged weeks in advance by Mrs. Vanderbilt with her cooks, butlers, and gardeners to avoid last-minute slip-ups. On such occasions, the hostess made it a point to blend the color of the flowers, the cloth, and the china. Thus, if yellow flowers were being used, the lace cloth would have a yellow satin undercover. The centerpiece might be an inlaid gold mirror and gilt vase, filled with fresh yellow roses. Scattered about the table would be six or eight smaller gold vases of flowers. The service would be gold-plated, and the china would be white, with a gold stripe and the family monogram in the center.
