Pack snacks!!! You might get hungry throughout the day and there is so much to do and see that you might forget, or not want to stop, to eat. I keep granola bars, almonds, and beef jerky with me to keep me nourished through the day. It also helps keep expenses down if you have something with you to nosh on! I know all the venues state no outside food allowed, but it isn't a problem if you conceal it well. They inspect bags but usually don't pat you down, and cargo short pockets can hold a lot!
