The Signature is one of the few places in Vegas that is a true hotel.  The hotel features three seperate towers, all with suite sized rooms.  The rooms feature possibly the most comfortable beds of any hotel, and a massive living space for you to enjoy during your stay (kitchenette, living room, desk).  The Signature is attached to the MGM Grand via several moving sidewalks, and is a nice way to get away from all the crazyness of dinging slot machines and smoking grandmas on the strip, while still being right in the middle of the lights.  It's truly an Oasis of luxury in Vegas.  You will not be disappointed here if you value relaxation and luxury over the mayhem of tables and slots.
