I'm typing this as I sit in my room at the property. The building is pleasant, with a very convenient, yet quiet location (It's in a wooded, pond-side area off Butler Blvd). Its aesthetics aren't too dissimilar from those of a Westin.
My standard room is comfortable and spacious, if not gargantuan. My understanding is that the 6th floor is the Club Level. What's somewhat disappointing is that the evening snacks are served from 4-6 p.m.; for those working late, this is not convenient.
Now that Jacksonville finally has a Starwood property, my chances of reaching Platinum are much improved; at that point, I'll let you know how I fare here in the upgrade game.
