Just for you info, we got moved to the Hilton Financial district. I don't know if this is considered an 'upper tier 4 star' but it certainly didn't feel like it. In fact we were made to feel like refugees from the Meridien. When we checked in at 3pm, we were told "don't know if we can find you a room, we're overbooked ourselves". After a long wait and a discussion with the manager, they found us a room. Unfortunately it was one of the dreaded ending in 00 rooms. Meaning one of the half size shoe box rooms next to the elevator. Terrible Terrible.
