I really need to get a life going here, so I'll make this brief.
Go, just go, to the next D23 Expo. As good as this one was, the next one is bound to be even better.
Buy and trade useless pins. Wear lanyards and dorky mouse ears. Drink $3 water. Eat $9 hamburgers. Stand in line for hours. Willingly hand over your camera and cell phone. Meet wonderful people. See wonderful things. Have a magical experience.
See you next year. (Get in line early if you want to get a voucher.)
