I stayed in an Executive Suite a few months ago. It was on the first floor directly over the hotel entrance (facing inward) with kind of an odd floorplan. The curtains didn't close properly so light seeped into the room at all hours from the atrium, not to mention the noise from the restaurant/bar and whatever conventioneering is happening in the lobby. I've been in Grand Suites on various floors and that is the better choice IMO.
