I got away from C2E2 pretty cheaply as well. I only ended up buying two t-shirts. And the first panel I went to on Friday night gave away books from all the authors so I got 6 free books which I might actually want to read so that was an added bonus. C2E2 has been steadily improving since it first started two years ago. A lot more vendors, more people attending, and better panels. My feet were dead as well from all that walking on concrete. I had to soak them and take Advil to recover.
