At one time the signature was a really nice place, those days are gone. It is an an antique, and not in a good way. My key card was unusable at least 2 times every single day I stayed there and I had to go to the front desk to get a new one. With the room being in tower 3 and the only open desk in Tower 2, not exactly convenient nor is it something you want to to in the first place. It is something that is very common there as expressed by the front desk staff. But going to the elevator and not being able to get to your floor, coming back from being out in vegas, not being able to get to your floor, or other times getting to the floor and not being able to get into the room, after a while just gets very old, to be honest it just plain sucks. The room wasn't dirty or anything like that but it was probably really nice in like 1995 or something, but it needs a serious makeover. Things like the chairs at the table, were so rickety they aren't really useable if you just want to sit down and have some coffee and do some quick work on your laptop. The safe didn't work, the carpet etc, like i said not "dirty" but not nice either. DO yourself a favor, stay in a place where you can at least get into your room without having to wait in line like you are checking into a hotel 2+ times a day. If you like standing in line and not being able to get into your room when you want to, probably a good place for you.
