To honor their values, their sacrifice and commitment to duty and country, Atlantis Casino Resort Spa is installing a new Gold Star Families Christmas Tree honoring the families of servicemen and women who sacrificed their lives while serving in the military. The tree lighting ceremony will be held at Atlantis Tuesday, at 5:30 p.m. on the second floor near Bistro Napa. The general public is invited to be a part of this historic event. The tree will be on display throughout the month of December.
