For a different perspective, I stayed at the Hilton and had one of the worst nights of sleep ever, I won't stay there again. I paid extra for the executive level and they put me in a room next to the maid's rest/supply area. The maid door was in dire need of lubrication, and apparently they shift change between 2 and 3 am. The door must have opened and closed 40 times during that hour, each one loud enough for me to hear in the room next door. First it woke me, then it kept me up on the most important night of my life. I interviewed on about 3 hours sleep.

The Holiday Inn just down the street is every bit as nice and costs less, although the nice 5 minute walk is now 15 minutes. Risk there though is higher chance of drunks wandering the halls screaming at 2am instead of the squeaky door :/.
