Had to pay for the tix, but they did a nice job with upgrading us . Given the chance to do it again, I'd rent a 17-55 2.8, I think the extra stop would have put my shutter up little closer to where it needed to be (>1/300). A lot of the images are softer than they appeared in the camera. I'll get a sample or two up when I get to my computer later.
That's a pretty awesome deal, plus the clip show is much better than the lake show right now.
One thing I would say is that often times opening up that extra stop is at the expense of dof and some of your soft images could have been from mis focus especially with a Rebel even at f4. Too bad you can go back tonight and play around again
