The three towers that comprise this spacious and well-appointed luxury resort adjacent to the MGM Grand are perhaps most notable for what they lack: a casino. Instead, developers have stockpiled modern junior, one- and two-bedroom suites with amenities such as whirlpool spa tubs, HD flat-screen televisions, two-line telephones, and open-air balconies. The well-trained staff manages the 24-hour concierge desk, 24-hour in-room dining, and pre-arrival services such as dinner or show reservations. Business travelers will appreciate the huge desks and free Ethernet access. With a secluded, gated entrance, the Signature also offers something even more unusual in Sin City—privacy.
