Mmm, well there's a few places. There are quite a few beautiful areas around the harbor if it's not too cold.
Otherwise, inside the convention is sort of broken into a hotel side and a convention center side. The hotel side is really pretty; on I think the third floor there's a nice gondola type thing that's really popular for photoshoots. We'd just have to coordinate the time to make sure there isn't another group meeting there at the same time. Also, on the first floor there's a fountain, and a small area near it.
