Hmmm... I wasn't really thinking photos at the time, but when I was there about a month ago for dinner I took a few minutes to wander around outside. After promptly noticing how all the doors were set to auto-lock (Hopefully that's not the case during the convention.) I remember seeing a small shrubbery area over by the pool, the service road area behind the hotel overlooking the river, and off to the side of the hotel is a lawn area....
*shrugs* Those are just what possibly comes to mind, but I'm not really a photographer.
