The Renaissance is just fine, if you're focused on getting the Marriott points. It's a pretty standard Renaissance, with nice rooms, minibar, etc. Because of the building's shape, some of the rooms are a bit different, so try to get there early and sweet talk your way into one of the larger rooms (nearer the center of the floor, I remember). Also, try to make sure you get a room facing the harbor, if you like to watch the ships, seaplanes, etc. The view from these room is much better, especially on the lower floors.
