Hi,
We were also at the July 16th WHW (and loved looking over the photos). Yes, it's a fun time, but I'd suggest getting there early for the Cracker Jack - it was all gone by the time we got there. However, there's plenty of cold lemonade and water, and chips & pop corn. As mentioned, they also gave caps to everyone, which was nice.
I happened to win one of the larger prizes, a complimentary photo session at SSR for our family. It was a great surprise, but there was one little problem - we were checking out the next morning. Thankfully the gents at SSR's photo desk were able to fit us in that following morning, after we had called Bell Services to take our luggage. Nothing like a hectic departure day, eh?
