I was there a while back. I enjoyed it for the most part, but I wish I had worn better walking shoes when I did go. Probably would have been more enjoyable had I not been looking for a place to sit every 10 blocks.
I hear you there...
We were just there again for NY ComicCon, we drove and taxi'd last year; walked and subway everywhere this time.
My knees and heels have been giving me a whole lot of trouble lately, so walking a convention all day and then having to walk to the subway stops after the show was a terrible idea. But we had a great time so it was all worth it...
Plus we had our first "exciting" experience with the subway this time, we're still not sure exactly what happened but for a while I was very worried a gun would show up and bullets would fly...
