In 1955, San Souci had become a corporation and was known as Sans Souci Hotel, Inc.

Apparently The Patio didn't do well as during this year its name was changed to The Rendezvous. In 1956, Hayes got involved in the property again and changed its name back to Gracie Hayes Lodge. Hayes was the first on the Strip in December 1956, to put up Christmas lighting around the entrance to her lodge. All mention of Gracie Hayes Lodge/Red Rooster clan disappeared after this year.

In August of 1958, Sans Souci filed bankrupcty in the amount of $1 million. Several plans were presented to Federal Judge Ross for reoganization.

The larger and modernized The Sans Souci Hotel Casino opened in March of 1960, with Joe Medure named as President.

The Sans Souci contained 100 deluxe rooms and apartments. It advertised a telephone in each room, refrigerated air-conditioning, a snack bar, and a swimming pool. In the front of the resort was Dinah's Pancake and Chicken House.
