Mandalay Bay adds elevator security after Las Vegas shooting

Mandalay Bay is adding to its security even as it cuts hours of other employees. People seeking to get on the elevators must now show their room key. The new policy applies to Delano as well, they said. The change comes after the Oct. 1 shooting that killed 58 and injured more than 500. Several major hotels on the Strip already had similar practices in place before the shooting.
