This year was great! I went to the one in 2006 when I was in my freshman year of high school, and I was so excited to see how much this convention has grown over the years! I really hope we end up in the RenCen again next year.
The biggest problems of mine were the elevators and the fact that CVS and the food courts weren't open long enough for me and my friends to have much of a food selection. I like Subway only so much. :/
