a brief history of the legendary las vegas hotel, which turns 50 this month. Jay Sarno changed LAS Vegas forever in August 1966 when he opened its first themed resort: Caesars Palace. Borrowing elements from the Roman Empire, Sarno followed the principle that no amount of excess was enough. In its first 50 years Caesars Palace has expanded from an opulent 14-story hotel with 700 rooms to a small city with six towers, 4,000 rooms, a 636,000-square-foot shopping mall, a 4,300-seat theater and nearly a dozen celebrity-chef restaurants. You can also still do a little gambling there.
