Las Vegas (AP) - Major gambling companies' ledgers have told the same, sinking story for a year: Fewer people are visiting casinos, their trips are getting shorter and they're not gambling as much. Casino construction has slowed or halted from one end of the Las Vegas Strip to the other, more than a dozen projects across the U.S. and abroad have been modified or dropped, and more than 40,000 new rooms in Las Vegas planned by some of the industry's biggest players are on hold.
