Personally, this is my favorite convention to attend, even more so than AX, or SDCC, or AM2, among others. It is so lax, but I always have plenty to do. It's really cozy and fun, and more 'intimate', if that's the right word?
There are lots of great environments for photo shoots, lots of activities, and if there isn't an activity for you then there is plenty of opportunity to make one! It is such a fun convention, the perfect way to start the new year.
